Paul Brian Portmann was stopped by a Nebraska trooper for driving onto the shoulder of the interstate highway in violation of Nebraska traffic laws. See Neb. Rev.Stat. § 60-6,142 (1993). As the trooper stood beside the driver’s door during *1033 the stop, he smelled a faint odor of raw marijuana coming from the interior of the car. The trooper completed a valid traffic stop, giving Portmann a warning. Before Portmann could leave, the trooper asked for consent to search Portmann’s car for drugs, weapons, large amounts of cash or alcohol. After the trooper made several attempts to get consent, Portmann made it clear that he wanted to be on his way. Instead of allowing Portmann to leave, the trooper took the drug detection dog from his patrol car and ran it around Port-mann’s car. The dog alerted to the rear of the car and a search yielded 70 packages of marijuana with a total weight of 248 pounds. Portmann moved to suppress the evidence, claiming the trooper did not have probable cause to conduct the war-rantless search of the car. Having found the smell of raw marijuana detected by the trooper at the outset of the traffic stop gave him probable cause to detain and search, the magistrate recommended denial of Portmann’s motion. The district court concurred in that finding and denied Portmann’s motion. Portmann entered a conditional guilty plea on the charge of possession with intent to distribute marijuana in violation of 21 U.S.C. § 841(a)(1) and received a sentence of 37 months with 60 months supervised release. Portmann appeals the denial of his motion to suppress. We affirm.
Portmann argues the district court erroneously denied his motion to suppress because the judge failed to conduct the de novo review of the magistrate’s Report and Recommendation on the contested issue of the trooper’s credibility required by the Federal Magistrates Act, 28 U.S.C. § 636(b)(1) and the Local Rules of the United States District Court for the District of Nebraska, Rule 72.4. We disagree. The statute contemplates that the court “ ‘will consider the record which has been developed before the magistrate and make [its] own determination on the basis of that record, without being bound to adopt the findings and conclusions of the magistrate,’ ”
United States v. Raddatz,
Portmann concedes the smell of marijuana would give the trooper probable cause to search his car,
