MINNEAPOLIS (AP) — A judge ruled that the arrest of a Minnesota man on a gun charge was justified in a case that has drawn attention because he was sentenced to life in prison as a teen in an high-profile murder case and spent 18 years in prison before his sentence was commuted.

Myon Burrell was charged after police in the Minneapolis suburb of Robbinsdale said they found a handgun and drugs during the stop Aug. 29.

The defense argued at a hearing in February that the stop lacked probable cause and that the gun and drugs should therefore be excluded.

In a ruling this week, Judge Peter Cahill found the testimony of the arresting officer credible, and said he would allow the gun and drugs as evidence. The officer testified that he saw Burrell driving erratically, and that when he stopped Burrell, smoke came out of the window and that he smelled a strong odor of burnt marijuana. Burrell failed field sobriety tests to determine whether he was driving under the influence, the judge noted.
