Kurt A. Smith аppeals from his judgment of conviction for trafficking in marijuana in excess of one pound. Specifically, Smith challenges the district court’s order denying his motion to suppress. For the reasons set forth below, we affirm.
I.
FACTS AND PROCEDURE
A police officer responding to a domestic dispute learned that the suspect had fled the scene on foot into a sparsely-pоpulated, wooded area. While the officer was searching for the suspect, he came across a car parked in a large pull-out area at the end of a road. When the officer flashed his spotlight toward the car, a man later identified to be Smith exited and walked toward the officer’s patrol ear. As Smith approached, the offiсer ascertained that Smith did not match the description of the domestic violence suspect. The officer began conversing with Smith about whether he had seen the domestic violence suspect and eventually asked Smith for identification. Smith agreed to give the officer his identification, but stated that it was in his car. The officer followed Smith as he returned to his ear to get his identification. Smith got into the driver’s side door, while the officer walked to the passenger side. The officer looked through the window and saw a marijuana pipe sitting on the front seat of the car. The officer asked Smith how much marijuana was in the car. Smith grabbed the pipe and stated that it was the only illegal thing in the vehicle.
Smith had a large dog in the back of thе car that was growling at the officer. The officer asked Smith to remove and restrain the dog so that he could search the interior of the ear. Smith grabbed a backpack from the car and used its straps to take the dog from the car. The officer, who noticed the car was filled with camping gear, asked Smith if he had anything else that he could use to restrain his dog, but Smith ignored his question and continued to use the backpack. With the dog restrained, the officer proceeded to search the vehicle. On the passenger seat, he found a zippered case which contained a tin with a small amount of marijuana inside. The officer then told Smith to place the dog back into the vehicle. Smith put the dog back in the ear but continued to clutch the backpack. The officer asked Smith why he was so attached to the backpack and, when Smith did not respond, the officer asked Smith to hand over the backpack. The backpack was partially open and the officer *118 found a square object wrapped in duct tape inside. When the officer asked Smith what the objеct contained, Smith told the officer to open it and find out. The object contained marijuana and the officer found additional marijuana elsewhere in the backpack.
Smith was charged with trafficking in marijuana in excess of one pound, I.C. § 37-2732B(a)(l)(A), and possession of drug paraphernalia, I.C. § 37-2734A(l). Smith filed a motion to suppress the evidence found in the backpack, arguing the warrantless search was unlawful. After a hearing, the district court denied Smith’s motion to suppress. The district court found that the officer had probable cause to arrest Smith at the time of the search and, therefore, the search was justified as a search incident to arrest. Smith was found guilty by a jury of both counts and was sentenced to a unified term of six years, with a minimum рeriod of confinement of one and a half years, for trafficking in marijuana in excess of one pound and a concurrent term of 180 days for possession of drug paraphernalia. Smith appeals, challenging the denial of his motion to suppress as to his judgment of conviction for trafficking in marijuana in excess of one pound.
II.
ANALYSIS
Smith argues that the district court еrred in denying his motion to suppress. Specifically, Smith asserts that the search of the backpack violated his Fourth Amendment right against unreasonable searches and seizures because the officer did not have a warrant for the search and the search did not fall into any exception to the warrant requirement. The standard of review of a suppressiоn motion is bifurcated. When a decision on a motion to suppress is challenged, we accept the trial court’s findings of fact that are supported by substantial evidence, but we freely review the application of constitutional principles to the facts as found.
State v. Atkinson,
The Fourth Amendment to the United States Constitution prohibits unreasonable searches and seizures. Warrantless searches are presumed to be unreasonable and therefore violative of the Fourth Amendment.
State v. Weaver,
The district court applied the Gant search of a vehicle incident-to-arrest exception in this ease. The district court found that, because the officer had probable cause to arrest Smith at the time of the search, the Gant exception applied. On appeal, Smith argues that the search incident-to-arrest exception should not apply in his case because he was not formally arrested at the time the search took place. The state argues that the search of Smith’s backpack falls into the search incident-to-arrest exception to the warrant requirement because, even though Smith was not formally arrested at the time of the search, the officer had probable cause to *119 arrest Smith at the time he searched the backpack.
We begin by noting that Smith objects to the search of the backpack and not to the search of the interior of the vehicle. At the time the officer searched the backpack, it was not physically within the interior compartment of the vehicle. The backpack was, however, part of the contents of the car and the officer watсhed Smith remove the backpack from the car’s back seat. Under these circumstances, it is immaterial that the search of the backpack occurred outside the vehicle’s compartment because the backpack was part of the original contents of the car and the officer saw Smith remove it. Therefore, we will treat the search of the backpack as we would a search of the car’s interior and contents.
We recognize that, unlike in
Gant,
Smith was not formally arrested until after the search of the backpack occurred. We must determine, therefore, whether the search ineident-to-arrest exception to the warrant requirement laid out in
Gant
applies to a search of vehicle which takes place prior to a suspect’s formal arrest. This is a matter of first impression in Idaho. In
Rawlings v. Kentucky,
The United States Court of Appeals for the District of Columbia has applied
Rawl-ings
to a case involving a warrantless search of a vehicle incident to arrest.
See United States v. Powell,
Based on Rawlings and Powell, we perceive no reason to treat the search of a vehicle incident to arrest differently from a search of a person incident to arrest with regard to the timing of the formal arrest. In this ease, the marijuana found in Smith’s backpack was not necessary to establish probable cause for his arrest. The officer had probable cause to arrest Smith for possession of drug paraphernalia prior to the search of the backpack because the officer *120 saw a marijuana pipe on the passenger seat of Smith’s ear. In addition, Smith’s formal arrest occurred immediately after the search of the backpack. Accordingly, although Smith was not formally arrested prior to the search of the backpack, this does not prevent the search of a vehicle incident-to-arrest exception to the warrant requirement laid out in Gant from applying in this case.
Under the second prong of Gant, it was reasonable for the officer to believe that Smith’s backpack contained evidence of the crime of arrest. The officer saw drag paraphernalia associated with the use of marijuana in plain sight on the front seat of Smith’s car. At the motion to suppress hearing, the officer stated that, in his experience, when he finds a marijuana pipe there are often drugs as well. In addition, the officer testified that his suspicions were aroused by Smith’s statement that the pipe was the only illegal thing in the ear. Smith’s actions in using the backpaсk to leash his dog and continuing to hug it after the dog was placed back into the car, Smith’s failure to answer the officer’s direct questions concerning the backpack, and -Smith’s nervous demeanor provided the officer with a reasonable belief that the backpack contained evidence of the crime of Smith’s arrest. Therefore, we hold that the officer had reasonable suspicion to believe, under Gant, that Smith’s backpack contained evidence of the crime of his arrest. Accordingly, the district court did not err in denying Smith’s motion to suppress on these grounds.
We note that the search of Smith’s backpack was also justified by another exception to the warrant requirement. The automobile exception to the warrant requirement authorizes a warrantless search of a vehicle when there is probable cause to believe the vehicle contains contraband or evidence of criminal activity.
United States v. Ross,
The Court noted that, based on the detailed accuracy of the informant’s tip, the officers had probable cause to search Ross’s entire vehicle. The Court went on to hold that an individual’s expectation of privacy in a vehicle and its contents may not survive if there is probable cause to believe that the vehicle is transporting contraband.
Ross,
The Idaho Supreme Court has applied the exception to the warrant requirement laid out in
Ross
to warrantless searches of automobiles.
State v. Gallegos,
Whether the search was incident to Smith’s arrest or pursuant to the automobile exception, probable cause is required. Probable cause is not measured by the same level of proof required for conviction.
State v. Fry,
In addition, Smith’s actions in using the backpack to leash his dog and continuing to hug it after the dog was placed back into the ear, failure to answer the officer’s direct questions concerning thе backpack, and nervous demeanor provided the officer with probable cause to believe that contraband might be found within the backpack. Under the Ross exception to the warrant requirement, the officer had probable cause to search Smith’s vehicle and was justified in searching any of the vehicle’s contents which may have concеaled contraband. It is immaterial that Smith removed the backpack from the car prior to the search as it was originally pai’t of the contents of the vehicle. Therefore, under the Ross exception to the warrant requirement, the officer’s actions in searching Smith’s ear and its contents were proper. Accordingly, we hold on these alternate grounds that the district court did not err in denying Smith’s motion to suppress.
III.
CONCLUSION
We hold that the district court did not err in denying Smith’s motion to suppress because it was justified under the search incident-to-arrest exception to the warrant requirement and the automobile exception to the warrant requirement. Accordingly, Smith’s judgment of conviction for trafficking in marijuana in excess of one pound is affirmed.
