A Clearlake man killed in a Lower Lake crash was Daniel Paul Gray, 29, the CHP said Tuesday.
Gray had been driving north on Highway 29 in Lower Lake early Saturday when he drove off the roadway and hit a tree. He died at the scene.
The crash was just after midnight, north of Marsh View Way.
Gray was not wearing a seat belt.
CHP officers on Tuesday still were investigating what led to Gray's driving the 2012 Chevrolet Malibu off the road.
