OPINION
Appellant Rafael Alvarado was convicted by a jury of possession of cocaine. Appellant plead true to the two enhancement paragraphs and the court assessed punishment at thirty-five years confinement in the Institutional Division of the Texas Department of Criminal Justice. We affirm.
FACTS
On July 14, 1993, Officer Leslie Wills of the Houston Police Department was on patrol when she saw appellant standing in an alleyway known for illegal narcotics activity. Wills testified that she recognized appellant because she had issued citations to him in the past and she knew there were outstanding warrants for his arrest. Wills decided to approach appellant because he had an outstanding warrant. As Wills approached appellant in her patrol car, she did not observe him engaging in any criminal activity. As she got out of her vehicle, however, Wills noticed appellant had -an object in his hand which he tried to hide with a baseball cap. The officer believed the object was a crack pipe and when appellant turned the object over to Wills at her request, Wills’s belief was confirmed. A field test on residue in the pipe was positive for cocaine.
VALIDITY OF STOP, SEIZURE, AND ARREST
1. Warrants not produced.
In his first point of error, appellant argues the trial court should have granted his motion to suppress because the State failed to introduce the warrants Officer Wills relied upon to approach and arrest appellant. In his motion to suppress, appellant states that his arrest and detention were without warrant and without probable cause, thereby violating his rights under both the United States and Texas Constitutions. U.S.Const. amend. IV; Tex. Const, art. I, § 9. 1
*872
When a defendant seeks to suppress evidence on the basis of a Fourth Amendment violation, the burden of proof is initially on the defendant.
Russell v. State,
In this case, appellant met his initial burden by showing that Officer Wills seized a pipe from appellant. The burden then shifted to the State to either produce the warrants used to effect the arrest and seizure of evidence, or to demonstrate the reasonableness of the warrantless arrest, or prove consent was free and voluntary. Because the warrants which are the subject of appellant’s complaint were not used to effect his arrest, the State was not charged with the burden of introducing them to the trial court. The warrants involved in this case were merely evidentiary items, testified to by Officer Wills, as the initial reason she decided to approach appellant. Therefore, appellant had the burden to produce the warrants if he wished to have them considered for appellate review. See Tex.R.App.P. 50. Because the outstanding warrants were only one basis for Officer Wills initial approach, and not appellant’s detention, the seizure of his pipe, or his arrest, we analyze those events under the law governing warrantless encounters.
2. Terry stop.
We therefore next turn to the propriety of appellant’s detention. It is well settled that a police officer may, in appropriate circumstances and in an appropriate manner, stop an individual for purposes of investigating possible criminal behavior even absent circumstances rising to the level of probable cause to make an arrest.
Terry v. Ohio,
Evidence pertaining to the detention in this ease was: Officer Wills initially testified that when she got out of her vehicle she saw appellant do something that indicated he was engaging in criminal activity, namely trying to conceal a crack pipe from her view. Later, without retracting her earlier testimony, Wills said she did not observe any activity on the part of appellant indicating he was doing something criminal. Wills further stated that at the time she stopped appellant, she recognized him and she believed him to have outstanding warrants. We find that viewed in the light most favorable to the trial court’s ruling, there was evidence to support the trial court’s implied finding that this was a valid investigatory stop.
3. Arrest.
We next consider the validity of appellant’s arrest. Appellant correctly states that when a defendant claims an arrest or search is conducted without a warrant, the State has the burden of establishing that probable cause and an exception to the warrant requirement existed.
Roberts v. State,
The evidence, viewed in the light most favorable to the trial court’s ruling, supports the judge’s decision to overrule the motion to suppress. We overrule Point of Error One.
MISSPELLED NAME
In his second point of error, appellant complains that the name on the outstanding arrest warrant is different than his name. The testimony, however, demonstrates that the name on the ticket that the warrant was issued on is spelled incorrectly. The outstanding arrest warrant is not part of the record on appeal and, therefore, we are precluded from considering any effect the misspelled name might have on the validity of appellant’s arrest. Moreover, our determination under Point of Error One, that this was a valid warrantless arrest, not one pursuant to a warrant, renders this point moot. We overrule Point of Error Two.
WEIGHT OF CONTRABAND
In his third and final point of error, appellant complains the evidence is insufficient to establish that he knowingly possessed cocaine, because the measured amount of 45.4 milligrams was less than the margin of error the test used to analyze the substance. In reviewing the sufficiency of the evidence, the appellate court must view the evidence in the light most favorable to the verdict.
Adelman v. State,
The Houston Police Department chemist testified that the weight of the residue in the crack pipe was calculated at 45.4 milligrams of cocaine, including adulterants and dilu-tents. The chemist further testified that the tests utilized to calculate the weight have a margin of error equivalent to plus or minus fifty milligrams. Appellant claims that since the margin of error exceeds the weight of cocaine found in the crack pipe, there is no real evidence of weight at all. He appears to seek a holding that any measured amount of contraband which falls within a test’s margin of error cannot, as a matter of law, constitute sufficient evidence to support a conviction.
This issue is one of first impression. It is well settled that possession of minute amounts of cocaine is sufficient to sustain a conviction, so long as the amount possessed is capable of being quantitatively measured.
Lavigne v. State,
CONCLUSION
We affirm the conviction.
Notes
. Our decision regarding the detention and arrest in this case is based on the testimony adduced at the hearing on appellant's motion to suppress evidence and that evidence is viewed in the light most favorable to the trial court’s ruling.
