The California Highway Patrol on Tuesday arrested a Mill Valley man on suspicion of fleeing the scene after striking a road-construction worker the day before, causing serious injuries.

The incident occurred on Highway 89 in a busy construction zone in Homewood, on Lake Tahoe’s west shore, about 1:35 p.m. Monday.

Following an investigation, CHP officers arrested Erich J. Griesemer, 60, of Mill Valley, in Tahoma, a west-shore community near Homewood, about 4:20 p.m. Tuesday.

According to the CHP report, for reasons still under investigation, a southbound red Toyota Tacoma pickup with a camper shell and lumber rack driven by Griesemer allegedly struck Ismael Mayorga-Torres, who was walking along the west side of Highway 89.

Mayorga-Torres, 51, of Sparks, Nev., was assigned to traffic control at the construction site. He was flown to a Reno hospital, where he remains in treatment for major injuries, said Peter Mann, public information officer at the Truckee CHP office.

CHP officers placed Griesemer in custody following his arrest and have filed charges in an injury-related hit-and-run traffic collision, the report said.

Mann said events leading to Griesemer’s arrest are “still part of the ongoing investigation and can’t be disclosed at this time.”

Anyone with information regarding the incident is asked to call the Truckee CHP office at 530-582-7570.
