Kevin Connery appeals from a criminal judgment entered on a jury verdict finding him guilty of possession of a controlled substance in violation of § 19-03.1-23, N.D.C.C. We affirm.
At approximately 8 p.m. on November 1, 1987, Highway Patrol Officer Scott Brand stopped a vehicle driven by Connery- on Highway 83 north of Bismarck because of a speeding violation. After obtaining Connery’s driver’s license, Brand returned to his patrol car, completed a traffic citation, and returned to Connery’s vehicle with a flashlight to have him sign the citation. Brand noticed an open beer can in the front seat and asked Connery and his passenger to step out and stand in front of the vehicle. Brand reached into the driver’s side of the vehicle, picked up the can, which was empty, and noticed a paper bag near the passenger’s side.
When Brand began walking around the vehicle to the passenger’s side to retrieve the paper bag, Connery ran from the front of the vehicle to the passenger door and grabbed something from under the seat. Brand told Connery to leave the object alone and step back, but Connery then ran to the rear of the vehicle. Brand observed that Connery, with his back toward him, was crouched over and reaching toward the center of his stomach and back to his pockets. Brand also noticed something that appeared to be wooden stuck in between Connery’s legs and thought that it could be a rifle or shotgun stock.
At this point, Brand drew his service revolver and told Connery to place the object on the ground and step away from it. Instead, Connery walked to the front of the vehicle and, according to Brand, “spun around,” thrust the object up in the air, and then placed it on the hood of the car. The object was a wooden box. When Brand asked Connery what was in the box, he responded, “just some marijuana.” Brand looked into the box and found a small amount of what appeared to be marijuana. Brand then placed Connery in the back seat “cage” of the patrol car.
With Connery secured in the patrol car, Brand returned to the front of Connery’s vehicle and, because it was an extremely windy evening, began looking on the ground for evidence that might have been blown from the box when Connery thrust it in the air. Brand found what appeared to be marijuana on the ground as well as a baggie containing marijuana directly in front of the car. Brand also saw an orange container rolling on the highway, retrieved it, and discovered another baggie containing marijuana inside. Brand returned to the patrol car and, after advising Connery that the material he had found would be analyzed, that the information would be submitted to the state’s attorney, and that charges might be filed, told Connery that he could leave.
Brand unlocked the back door of the patrol car for Connery. As Brand stepped back to let Connery out, he noticed two *653 more baggies of what appeared to be marijuana lying on the ground beside the patrol car. Brand asked Connery where those baggies had come from and Connery responded that he “threw it out.” Connery then left in his vehicle.
On December 16, 1987, Connery was charged with possession of marijuana in an amount weighing more than one-half ounce but less than one ounce, a class A misdemeanor. Connery moved to suppress the two statements he made to Brand implicating his ownership of the marijuana on the ground that he had not been advised of his rights under
Miranda v. Arizona,
Connery asserts on appeal that the trial court erred in refusing to suppress the statement he made as he was leaving the patrol car; that the evidence is insufficient to sustain the verdict; and that his right to a speedy trial was violated.
MIRANDA
We begin by noting the arguments the parties did not present either to the trial court on the suppression motion or to this court on appeal. The State did not assert that Connery’s initial response when Brand, with gun drawn, asked him what was in the box, should have been admissible as falling within the public safety exception to the
Miranda
requirement.
See New York v. Quarles,
Miranda
warnings are required only when a person is subject to “custodial interrogation.”
State v. Newnam,
While roadside questioning of a motorist incident to a routine traffic stop does not constitute custodial interrogation
[Pennsylvania v. Bruder,
- U.S. -,
Brand placed Connery in the back seat of the patrol car while he completed his search of the area. Brand returned to the patrol car and told Connery that the material he found would be analyzed, that the information would be forwarded to the state’s attorney, and that he might be formally charged. Brand also told Connery that he would not be “taken in,” but would be allowed to leave, and Connery was in the process of leaving the patrol car to return to his own vehicle when he made the incriminating statement. At no time dur
*655
ing this scenario was Connery placed under formal arrest. Although Brand may have had probable cause to place Connery under arrest, law enforcement officers are under no constitutional duty to halt the questioning of a suspect and place that person under arrest the moment they have the minimum evidence necessary to establish probable cause.
See United States v. Hudgens,
SUFFICIENCY OF EVIDENCE
In challenging the sufficiency of the evidence on appeal, the defendant must show that the evidence, when viewed in the light most favorable to the verdict, permits no reasonable inference of guilt.
State v. Jacobson,
Connery asserts that there was no evidence to show that he possessed the orange container containing marijuana which Brand found rolling along the highway north of his vehicle. Brand testified that it was possible the container could have been thrown from a passing vehicle, but that it was “highly improbable.” We believe that there was sufficient circumstantial evidence for the jury to find that Connery possessed the marijuana in the container. It was a windy evening and the container was found in the general vicinity of other similar contraband. We conclude that the evidence was sufficient to sustain the verdict.
SPEEDY TRIAL
Resolving a claim of violation of the constitutional right to a speedy trial requires evaluation of four factors: length of delay, reason for delay, defendant’s assertion of the right, and prejudice to the defendant.
State v. Littlewind,
The criminal complaint against Connery was filed on December 18, 1987. He was served with the arrest warrant on February 3, 1988. Connery filed a motion asserting his speedy trial right on March 22, 1988. Trial was held on June 23, 1988. The reason for the six-month delay between the issuance of the complaint and the trial was due mainly to Brand’s absence from the state while on military leave with the National Guard. After Connery filed his demand for speedy trial, the State moved, under Rule 15(a)(3), N.D.R.Crim.P., for an order allowing the deposition of Brand for the purpose of perpetuating testimony. In the alternative, the' State sought a continuance of the scheduled trial date from June 2 to a date after June 10, 1988, when Brand would be available. Connery opposed both motions. In the interim, a telephone deposition was taken of Brand for purposes of the suppression motion. Connery claims he was prejudiced because during the trial, Brand could not recall “what specific steps he took to stop *656 the Defendant’s vehicle, where his vehicle was located in relation to the defendant’s vehicle, or whether or not he had searched the Defendant before placing him in the patrol vehicle cage.”
Balancing the relevant factors, we conclude that these circumstances are insufficient to establish a violation of Connery’s right to a speedy trial. The six-month delay in this case is not unduly excessive. The delay was occasioned by the absence of an essential witness. A missing witness can serve as a valid reason to justify an appropriate delay of trial
[see Barker v. Wingo,
Moreover, we are not impressed by Connery’s claim of prejudice. Connery has not explained to us how Brand’s inability to recall the peripheral circumstances of the traffic stop affected any material issue that was present in his trial for possession of a controlled substance.
See State v. Erickson,
Accordingly, the judgment of conviction is affirmed.
Notes
. In
New York v. Quarles,
. In
Oregon v. Elstad,
Notwithstanding the
Elstad
Court’s partial reliance on the interceding
Miranda
warning in that case, several courts have read
Elstad
to strongly suggest that a
Miranda
violation without actual coercion will not taint evidence derived from a confession no matter what form such evidence takes.
See United States v. Cherry,
Although Connery has not raised the possible application of the “fruit-of-the-poisonous-tree" doctrine in this case, we could address this issue if it constitutes obvious error affecting substantial rights of the defendant under Rule 52(b), N.D.R.Crim.P. While it is a close question whether, under
Elstad,
Connery's second statement would be considered "tainted" by his unwarned prior statement thus rendering it inadmissible, we do not believe that this issue rises to the level of obvious error.
See State v. Prigge,
. We do not suggest that Brand was unjustified in drawing his weapon under these circumstances.
