(KNZA)--Two people were killed, and two others injured, in a single-vehicle late Saturday night Jefferson County roll-over wreck.

The Kansas Highway Patrol says killed in the wreck on K-237, north of 50th Street, were 21-year-old Oskaloosa resident Luke Puccinelli and 46-year-old Christopher Webb of Topeka.

The Patrol reports the two were passengers in a northbound pickup truck driven by 43-year-old John Lewis, of Ozawkie, which failed to negotiate a curve.  The vehicle left the roadway and overturned several times, coming to rest on the driver's side.

Puccinelli and Webb were pronounced dead at the scene.

Lewis and another passenger, 20-year-old Nortonville resident Gavin Lewis, were transported by ambulance to Topeka's Stormont-Vail Hospital with suspected serious injuries.

The Patrol says Lewis was the only occupant wearing a seatbelt when the wreck happened shortly after 10:15 Saturday night.
