After a driver failed to signal before shifting lanes on Danbury Road April 24, the passenger in her car got caught with 2.5 ounces of suspected marijuana.

Police stopped the southbound 2014 Kia Forte a little after midnight near Westport Road. The investigating officer smelled marijuana in the car and conducted a vehicle search, police said. The search yielded 2.5 ounces of suspected marijuana — a misdemeanor amount.
