A police report released Friday identified the driver in last weekend’s deadly hit-and-run accident as Joshua I. Walton, 24, of Lawrence.

According to the report, the car he was driving struck and killed pedestrian Ryan M. Kanost, 22, at 1:09 a.m. Saturday at 13th and Kentucky streets. The report lists two factors that the officer believed contributed to the wreck: Walton’s failure to yield to the pedestrian and “reckless/careless driving.”

Walton initially left the scene but turned himself in later in the day. He was interviewed but has not been arrested or cited, pending a review of the case by Dist. Atty. Charles Branson’s office.

The report released Friday did not contain any indication that alcohol or drugs were a factor. Police said earlier this week they were awaiting lab test results.

Branson said as of Friday he had not yet received reports on the case.

Friends and family described Kanost, a Kansas University senior, as extremely intelligent and headed for medical school.

Friends and witnesses said he was walking with three other friends from Gertrude Sellards Pearson Hall, 500 W. 11th St., to a friend’s house near 14th and Kentucky streets.

They looked to the right before crossing the one-way street and saw a car that seemed to be in the distance; the car changed lanes once but appeared to be speeding, said Brandon Seitzer, Kanost’s roommate, who was with him when he was struck by the car.

Another witness said he was crossing Kentucky Street about one-third of a block north of 13th and Kentucky streets. He looked to the south and saw a few people crossing Kentucky Street from west to east at the corner of 13th Street. He saw several people in the east lane of the one-way street and one person walking behind them in the west lane, when a car approached “very quickly” and struck Kanost with the front right side of the vehicle.
