A Petaluma man has been sentenced to probation and community service in the death of a 13-year-old boy during a birthday trip to Lake Mendocino in 2012.
Michael Lee Krnaich, 42, earlier had pleaded guilty to one count of felony child endangerment. He initially was charged with two counts.
Trevor Smith was run over and killed while pushing Krnaich's Chevrolet pickup down an offramp after it ran out of gasoline.
Krnaich had eight children, ages 9 to 13, push his truck and boat trailer after it stalled on Highway 101 just south of the Lake Mendocino Drive turnoff, according to testimony at his preliminary hearing. The group was headed to a birthday party for Krnaich's daughter.
Smith was killed when he slipped, fell and was crushed by the trailer as the rig picked up speed.
