A routine sobriety checkpoint stop in American Fork Canyon yielded a diaper bag containing methamphetamine and marijuana, and landed a mother behind bars.

Utah County Sheriff's Sgt. Spencer Cannon said Wednesday that deputies, along with Utah Highway Patrol and state and federal park officers, had set up the checkpoint on Highway 91 just east of the Timpanogos Cave National Monument this past weekend.

While most of the estimated 900 cars traveling through the checkpoint between Saturday afternoon and early Sunday morning were quickly cleared, officers delayed drivers who showed signs of impaired driving; the woman, who was with her child, was among the latter.

The woman — arrested after officers found the drugs inside her child's diaper bag — was among 19 people arrested on drug and alcohol violations, Cannon said.

In another case, a man was arrested after his blood-alcohol content was tested at 0.166, more than double the legal limit. With him in the car were his three sons, ages 8, 10 and 12; they eventually were turned over to their mother, who was divorced from their father.
