CASPER â The son of a Wyoming Department of Transportation employee killed by a street sweeper is suing the machineâs manufacturer, court records show.
Shirley Samuelson died in August when a street sweeper she had just parked on Highway 22 in Teton County rolled downhill and ran her over. She was 62.
The sweeper, made by Kansas-based SB Manufacturing Inc., was equipped with an emergency braking system. Samuelson had reportedly parked the sweeper she was using on a turnout on the highway, pulled the parking brake and turned the engine off before getting out to speak with a coworker.
While Samuelsonâs back was turned, court filings state the sweeper started rolling downhill. It ran over her, then crossed both lanes of the highway before hitting a cliff face on the opposite side and stopping. Samuelsonâs spine was fatally fractured and she sustained multiple injuries to her head and chest.
