AP – Authorities have identified a man killed in a fall last week from a northeast Kansas bridge, but they’re still investigating how it happened.

The Kansas Highway Patrol on Monday identified 37-year-old William Bratton Jr., of Junction City, as one of three drivers involved in a crash on an icy Kansas 18 bridge over the Kansas River near Manhattan.

The patrol says Bratton lost control of his pickup around 5:45 a.m. Friday and struck another vehicle. Bratton’s truck was then hit by a third vehicle.

Bratton got out of his truck to check the damage and went off the bridge, landing on the rocky river bed about 30 feet below.

The patrol says Bratton may have slipped, or may have jumped to avoid being hit by other vehicles.
