An accident report released Wednesday lists a driver’s “inattention” and “failure to yield” as the only apparent contributing factors in a collision last week that seriously injured a local mail carrier as he walked downtown.

Lawrence police have forwarded a report from the accident to District Attorney Charles Branson’s office to review whether the case could warrant any criminal charges. But the traffic report does not give any indications that drugs or alcohol played a role in the collision.

Postal worker Jerry L. Totten, 56, was struck by a pickup truck while crossing in a crosswalk at Seventh and New Hampshire streets.

He was taken by air ambulance to Kansas University Hospital in Kansas City, Kan., where he was listed in serious condition Wednesday.

The truck’s driver, Gale T. Willey, 56, of Lawrence, was not cited.

Branson said Wednesday that he had not yet reviewed the case.
