Dеfendants Martin Cardenas and Julian Rivera-Chacon were tried jointly in the United States District Court for the District of New Mexico. A jury rendered guilty verdicts on all counts in the indictments: conspiracy to distribute cocaine in violation of 21 U.S.C.A. § 846 (1981); possession with intent to distribute cocaine in violation of 21 U.S.C.A. § 841(a)(1) (1981); aiding and abetting in violation of 18 U.S.C. A. § 2 (1969); possession of a gun by an illegal alien in violation of 18 U.S.C.A. § 922(g)(5) (Supp.1988); shipping, transporting, or receiving a firearm with intent to commit an offense punishable by imprisonment for a term exceeding one year in violation of 18 U.S.C.A. § 924(b) (1976); and carrying a gun during a drug trafficking crime in violation of 18 U.S.C.A. § 924(c) (Supp.1988).
Defendant Cardenas seeks reversal of the cocaine convictions, alleging an inadequate foundation for the admission of the cocaine based on the incomplete chain of custody and material alteration of the cocaine. In addition, Cardenas appeals his convictions under 18 U.S.C.A. § 922(g)(5) and 18 U.S.C.A. § 924(b) alleging insufficiency of evidence of рossession of a firearm, and the erroneous definition of “carrying” under 18 U.S.C.A. § 924(c) used by the trial court.
A. FACTS
On July 9, 1987, Martin Cardenas and Julian Rivera-Chacon were arrested in the underground parking lot in the area of the (then) Regent Hotel located in Albuquerque, New Mexico. Lawrence Villas also was arrested and indicted along with Rivera-Chacon and Cardenas. Villas entered into a plea agreement with the government and pled guilty to reduced charges in exchange for testifying against Cardenas and Rivera-Chacon. The evidence produced at trial culminating in guilty verdicts is as follows.
For several months prior to the arrests, Villas was under investigation by the Socorro Police Department for drug trafficking. Ray Mares, one of its law enforcement officers, supplied Villas’ name to Lieutenant Lundy of the Bernalillo County *1530 Sheriff’s Department. Lieutenant Lundy, in turn, enlisted the aid of Greg Gunter and Eddie Montoya, also of the Bernalillo County Sheriffs Department, in the investigation of Villas.
At trial, Villas testified that Rivera-Cha-con was his sole source of cocaine and that they had planned the drug transaction. On July 9, Rivera-Chacon and Cardenas were in the parking lot to sell cocaine to Gunter and Montoya and that he, Villas, was merely the go-between. Villas testified that he approached Cardenas’ vehicle as planned; that Rivera-Chacon gave Villas a sample of the cocaine which was wrapped in currency for Gunter to try prior to the sale; that Villas took the sample up to the hotel room; and that Gunter and Montoya simulated snorting the cocaine. Villas further testified that Gunter, satisfied that the “coke” was good, left the hotel with him to complete the transaction in the parking lot. They looked for Cardenas’ truck, but it had moved. They got into Villas’ truck to try to find Cardenas and Rivera-Chacon. Ultimately, the operation concluded when Officer Ruben Garcia's vehicle blocked-in two vehicles. The first vеhicle contained Villas and undercover Officer Gunter. The second vehicle contained Cardenas as driver and Rivera-Chacon as passenger. Villas, Cardenas and Rivera-Chacon were all arrested at the scene.
Officers Montoya, Gunter and Garcia of the Bernalillo Police Department, Officer Mares of the Socorro County Sheriff’s Office, and Special Agent Ortiz of the United States Bureau of Alcohol, Firearms and Tobacco, were all present. Lieutenant Lundy, searching Rivera-Chacon, found a gun hidden in his boot. Officer Garcia, conducting a full inventory search of Cardenas’ truck, discovered a .25 caliber handgun behind a potato chip bag in an open dashboard compartment on the driver’s side of the car; the open compartment was inches from the steering wheel, within an effortless reach of Cardenas. Under the front seat, Garcia found a brown paper bag containing a plastic sack with a white substance inside. Garcia handed the brown paper bag containing the plastic sack, and the .25 caliber handgun to Officer Gunter. From this moment, Officer Gunter had sole physical custody of this evidence.
Officer Mares testified that Gunter showed him a plastic sack containing a white substance. Mares was too busy to inspect the substance. He testified that he did not see a brown paper bag, nor did he see Garcia give the substance to Gunter. In addition, at trial Officer Mares could not absolutely identify the plastic sack containing the white substance as the plastic sack that Gunter displayed at the scene; however, he did state that the plastic sack exhibited at trial in every respect resembled the sack displayed to him at the arrest. No field test was performed on the substance. Officer Garcia accompanied Gunter to the station with the seized evidence. At the station, Mares assisted Gun-ter in tagging the evidence. Gunter then, unobserved, carried the sealed evidence bags to the evidence room on the third floor of the station. The evidence technician testified that no brown paper bag was submitted to her; that she is obligated to accept any evidence given her; and that ultimately the police officers decide what is evidence and what is not.
Since Officer Gunter committed suicide one month prior to the trial, he was not available to testify.
I.
Defendant alleges that the plastic sack containing cocaine was improperly admitted into evidence on two bases: (1) the government failed to provide a sufficient chain of custody; and (2) there was a material alteration of the evidence. We disagree.
The standard of review of an appellate court when deciding the proper admission or exclusion of evidence at trial is abuse of discretion, defined in this circuit as an arbitrary, capricious, whimsical, or manifestly unreаsonable judgment.
United States v. Wright,
Controlling the admission or exclusion of real evidence at trial, Fed.R.Evid. Rule 901(a) provides that “[t]he requirement of authentication or identification as a condi *1531 tion precedent to admissibility is satisfied by evidence sufficient to support a finding that the matter in question is what its proponent claims.” The rationale is that in the absence of showing that the evidence is what its proponent alleges, the evidence is simply irrelevant. E. Morgan, Basic Problems of State and Federal Evidence, 327 (5th ed.1976); see also, 7 J. Wigmore, Wig-more on Evidence § 2129 at 703 (Chad-bourn rev.1978) (authenticity is an “inherent logical necessity”).
The condition precedent to the admission of real evidence is met by providing the proper foundation. If the proffered evidence is unique, readily identifiable and relatively resistant to change, the foundation need only consist of testimony that the evidence is what its proponent claims. E. Cleary, McCormick on Evidence § 212 at 667 (3d ed.1984). However, when the evidence, as here, is not readily identifiable and is susceptible to alteration by tampering or contamination, the trial court requires a more stringent foundation “entailing a ‘chain of custody’ of the item with
sufficient completeness
to render it
improbable
that the original item has either been exchanged with another or been contaminated or tampered with.” (Emphasis added.)
Id.
at 668;
accord United States v. Luna,
This circuit’s controlling test for the admission and exclusion of real evidence under Fed.R.Evid. Rule 901(a) was clearly enunciated in
Reed v. United States,
The cocaine, not uniquely identifiable, requires a sufficient chain of custody to support its admission. However, the chain of custody need not be perfect for the evidence to be admissible.
United States v. Mora,
On appeal, defendant alleges that there was an insufficient chain of custody to support the trial court’s admission of the cocaine since Officer Gunter, who had custody of it from the time of its initial seizure until he delivered it to the evidence room, was unavailable to testify. Based on this, defendant contends that the cocaine should not have been admitted since there was a “substantial break in the chain.”
From the moment Officer Garcia seized the cocaine from Cardenas’ truck, its whereabouts were accounted for. Testimony at trial by Officers Garcia and Mares shows that there was no substantial break in the chain. Upon seizing the cocaine, Officer Garcia handed it to Officer Gunter who, in turn, displayed it to Officer Mares. Admittedly Officer Mares could not absolutely identify the plastic sack containing white powder offered at trial as that seized from the truck. However, given that the plastic sack was not uniquely identifiable and considering his testimony that the evidence at trial in every respect resembled the evidence seized from the truck, the lack of absolute identification does not amount to an insufficient chain of custody.
See
*1532
United States v. Brewer,
The fact that Officer Gunter was not available to testify is not determinative of the admissibility of the cocaine since the whereabouts of the cocaine was accounted for from its original seizure from Cardenas’ truck until it was offered as evidence at trial. There is no rule that the prosecution must produce
all
persons who had custody of the evidence to testify at trial.
Gallego,
Defendant also alleges that the evidence was “materially altered” and, as such, should not have been admitted. We disagree. The fact that the brown bag was not secured as evidence does not equate with material alteration.
Officer Garcia testified that when he found the plastic sack containing cocaine it was in a brown paper bag. (At trial, a brown paper bag was exhibited to demonstrate how it could conceal the identity of the cocaine.
1
) When Officer Gunter showed the cocaine to Officer Mares, the paper bag was gone. The reasonable inference is that the paper bag was inadvertently discarded, not that Officer Gunter tampered with the plastic sack of cocaine in the presence of four other law enforcement officers from three different departments. No evidence elicited at trial pointed to the alteration of the cocaine itself; and so long as the relevant features remain unaltered, the evidence is admissible.
United States v. Skelley,
“ ‘Absent some showing by the defendant that the [evidence has] been tampered
*1533
with, it will not be presumed that the investigators who had custody of [it] would do so.’ ”
United States v. Wood,
The cocaine was properly admitted. Nothing in the record suggests that its admission was arbitrary, capricious, or unreasonable to warrant a finding of abuse of discretion.
II.
Defendant Cardenas appeals from his convictions under 18 U.S.C.A. § 922(g)(5) and 18 U.S.C.A. § 924(c). As to 18 U.S.C. A. § 922(g)(5), he contends there was insufficient evidence to prove possession of a firearm; as to 18 U.S.C.A. § 924(c), he contends there was insufficient evidence to prove possession and carrying of a firearm during and in relation to a drug trafficking crime. We disagree.
In determining the sufficiency of evidence to sustain a guilty verdict, the appellate court must consider whethеr there is sufficient evidence, both direct and circumstantial, along with the reasonable inferences therefrom, from which a jury may find a defendant guilty beyond a reasonable doubt.
United States v. Hooks,
Admittedly, there is no evidence in the record that Cardenas was in actual possession of a firearm; however, possession in fact is not a prerequisite of his conviction, constructive possession being sufficient. As recently defined in this circuit, “ ‘[a] person in constructive possession of an item
knowingly
holds the power to exercise dominion and control over it.’ ”
United States v. Medina-Ramos,
Citing Medina-Ramos, Cardenas argues that in addition to knowingly holding the ability to control an object, there must be an act by which that ability is manifested and implemented. We agree. The placement of the gun within inches of Cardenas’ hands, together with the act of concealment of the gun behind the potato chip bag, satisfy the requisite act manifesting Cardenas’ power to exercise dominion and control. Cardenas also argues that the fact that he made no furtive movements when approached by police officers negates possession. We disagree. Cardenas' truck was blocked in and he was surrounded by police officers from three different departments. His wisdom in seeing the futility of the use of the gun during his capture does not negate ultimate possession during the commission of the drug trafficking offense. Indeed, there was sufficient evidence to support the jury’s determination that Cardenas was in possession of a firearm and we so hold.
III.
For the first time in this circuit, the meaning of “carrying” to support a conviction under 18 U.S.C.A. § 924(c) must be construed.
2
Cardenas asserts that carrying firearms means exclusively to “wear, bear, or carry them
upon the person
or
in the clothing
or
in a pocket,
for the purpose of use, or for the purpose of being armed. . . .” (quoting
Black’s Law Dictionary
194 (5th ed.1979) (emphasis added)). He contends that since he did not carry “upon the person” or “in the clothing,” he was invalidly convicted under 18 U.S.C.A. § 924(c), and cites
United States v. Robertson,
As a preliminary matter, we point out that since Cardenas failed to object to the jury instruction’s definition of carrying, we may only entertain this issue on appeal if we find plain error. Jury Instruction No. 17 reads in part, “[y]ou are also instructed that the word ‘carry’ includes when a defendant in possession of a firearm transports the firearm or causes the firearm to be transportеd.” (Emphasis added.) We find no error in this instruction for the reasons set out below.
In construing the scope of a statute, we must first consider its language.
Russello v. United States,
Whoever, during and in relation to any crime of violence or drug trafficking crime, including a crime of violence or drug trafficking crime, which provides for an enhanced punishment if committed by the use of a deadly or dangerous weapon or device, for which he may be prosecuted in a court of the United States, uses or carries a firearm, shall, in addition to the punishment provided for such crime of violence or drug trafficking crime, be sentenced to imprisonment for five years....
(Emphasis added.) Since we find the statutory language devoid of any guidance on the scope of “carrying,” we look next to its legislative history. The record of the hearings and floor debates discloses that Congress made no attempt to define the scope of “carrying.” Therefore, in an effort to construe what Congress intended, we apply the long-honored rule of statutory construction,
expressio unius est exclusio al-terius
(the expression of one thing is the exclusion of others), and hold that mere transportation of a firearm is not within the purview of § 924(c)(1).
See Becker v. United States,
We find further support for our position in 18 U.S.C.A. § 924(b), 4 the subsection immediately preceding § 924(c), in which Congress explicitly provided that “[wjhoever, with intent to commit therewith an offense punishable by imprisonment for a term exceeding one year, ... ships, transports, or receives a firearm ... in interstate or foreign commerce,” shall be in violation. (Emphasis added.) Surely, Congress knows how to use “transports” when it choоses; in § 924(c) it did not so choose, and we do not choose to legislate on the matter. 5 *1535 However, our analysis does not end here. We have decided what carrying is not, but not yet what it is.
A careful reading of Jury Instruction No. 17 shows that the jury was instructed to find a simultaneous
possession
and
transportation
for the accused to be guilty of carrying under § 924(c); it does not equate transportation with carrying.
6
Defendant contends that “carrying” equates only with “bearing on the person or clothing.” We disagree.
7
We do admit that criminal stаtutes will not be construed to include anything beyond their letter.
United States v. Bass,
In an effort to construe the Congressional intent at the time of the enactment of § 924(c), we must begin our analysis with the meaning of “carrying” in 1968.
8
See e.g., Perrin v. United States,
We AFFIRM the conviction under 18 U.S.C.A. § 924(c).
Notes
. Essentially, it is uncontroverted that at the time of the seizure the plastic bag containing cocaine was found in a brown paper bag. Although thе defendant did not appeal on the basis of due process violation, the government cited
United States v. Obregon,
. We attempt this based on a deаrth of case precedent in other circuits as well.
. The wisdom of the government’s silence evades this court; such silence speaks of a failure to appreciate its duty to this court and to the principles of justice.
. Cardenas was convicted under § 924(b) but does not appeal on that basis.
. In
United States v. Barber,
. In
Barber, the
judge instructed that a " 'defendant is considered to have carried the firearm if he conveyed, transported or took the firearm with him. . . .’"
Id.
at 1244, n. 2, (quoting
United States
v.
Dixon,
. Although Cardenas urges this court to adopt his interpretation of
Robertson,
. 18 U.S.C. § 924(с) was originally enacted in 1968 as part of the Gun Control Act of 1968, but not included in the original Gun Control bill.
. Because “carrying" was judicially interpreted before the enactment of the 1968 version of § 924(c), we find it to be a legal term and "legal terms in a statute are presumed to have been used in their legal sense,” absent Congressional intent to the contrary. Sutherland, § 47.30; see also § 50.03 and accompanying citations (common-law definitions carry over to statutes dealing with the same or similar subject matter).
