Bay City murder suspect injected woman with heroin, then shot her on I-75, codefendant says

BAY CITY, MI — When a woman he had a crush on called him asking for help in getting a friend out of town, Aaron M. Wyse jumped at the opportunity. As he drove south out of Bay County on Interstate 75, the two women were initially chummy in his SUV’s backseat.

They didn’t get far before Wyse heard a gunshot from behind him. Turning around, he saw one woman was dead, the other holding a pistol in her hand. The shooter, Britany A. Letourneau, told Wyse she’d shot the other woman because a dose of heroin was taking too long to kill her.
