Authorities are investigating the death of a man who fell off an I-15 overpass onto Lake Mead Boulevard this morning as a possible suicide.
He was found on westbound Lake Mead about 8:45 a.m. and he was pronounced dead at the scene, said a Nevada Highway Patrol spokeswoman. Witnesses said the man was walking along Interstate 15 South, which runs over Lake Mead.
Two lanes of westbound Lake Mead were closed for a couple of hours.
