Franklin County Sheriff’s officers are looking for a man suspected of sexually assaulting a 14-year-old Kansas City, Mo., boy Monday night on Interstate 35 as the boy was walking to a gas station after his family had car trouble in the winter storm.

Undersheriff Steve Lunger said the boy’s family had car problems about 10 p.m. Monday about a mile south of I-35’s junction with Kansas Highway 68, just east of Ottawa. The boy started walking toward the nearest gas station when a man stopped and asked the boy if he wanted a ride.

The boy got into the truck, and the man sexually assaulted him. Then the suspect made the boy get out of the truck, Lunger said.

The boy then walked to the gas station and returned to his family.

Lunger said officers are looking for a white man between the ages of 26 and 28 with dark brown hair, blue eyes and a medium build. The suspect does not have facial hair and was driving a medium-sized pickup truck, although no color of the vehicle was given.

Investigators are asking anyone who might have seen something from 9 p.m. to 10:15 p.m. Monday in the area of I-35 to call 785-242-3800 and ask for Detective Bob Moews.
