WATFORD CITY, N.D. - A Florida man accused of killing three people in a Divide County crash changed his plea to guilty Monday.
William Koehler faces three felony charges of manslaughter after police say he caused a crash on Highway 5 in August.
Court documents say Koehler rear-ended a vehicle stopped at a construction site. The documents also say Koehler admitted to law enforcement he had been on his phone, and an investigation concluded he was driving more than 60 miles an hour upon impact.
One adult and two children were killed in the crash.
A sentencing hearing has been set for May.
