The driver accused of fatally running over an 8-year-old Longmont girl on her bike told police he thought he’d run into the curb until he saw the girl’s stepfather waving at him, according to an arrest affidavit released Friday.

Kyle Kenneth Couch, 20, of Longmont, turned right onto Longmont’s 17th Avenue on a red light at the same time Peyton Knowlton rolled into the Alpine Street crosswalk on May 20. The girl died from her injuries.
Couch turned himself in to police Friday morning on an arrest warrant listing charges including vehicular homicide and driving under the influence of drugs.
Longmont police this week revealed — more than two months after the crash — that they suspect Couch was under the influence of marijuana at the time, based on three blood samples, officer observations and the smell of unburned marijuana inside his Ford F-250 pickup.
