Lake Geneva police Friday identified the Mukwonago dump truck driver who was killed in an accident Thursday.

Todd Klauser, 58, was driving a truck owned by Sobczyk Trucking of Big Bend, police Lt. Ed Gritzner said in a news release.

At about 8:39 a.m. Thursday, police responded to an accident involving the dump truck at the ramp of westbound Highway 50/southbound Highway 120 and eastbound Highway 12.

Klauser died at the scene, police said Thursday. The dump truck sustained severe damage.

Gritzner said in an email Saturday, "The dump truck exited onto the off ramp, left the roadway and rolled." 

He said they will not know how many times the truck rolled or at what speed until Wisconsin State Patrol completes the crash reconstruction. 

Police are investigating the cause of the crash.
