A 22-year-old Ogden motorcyclist was upgraded to serious condition on Thursday, two days after he was struck by a minivan that then sped away.

Ogden police Lt. Nathan Cline said police still were looking for the minivan, described as possibly a Chrysler, dark blue or dark green, with a Utah handicapped license plate.

The collision occurred about 3:30 p.m. Tuesday near 4100 Harrison Blvd. Both the motorcyclist, Sean Lisonbee, and the minivan were southbound when the minivan reportedly struck the motorcycle, dragged its rider about 200 feet, and then sped away.

Lisonbee, who was not wearing a helmet, suffered shoulder and internal injuries.

Anyone with information on this case is asked to call OPD at 801-629-8060.
