SAN JACINTO - Sheriff's investigators are looking for three men tied to the home invasion robbery of a family as they prepared to go trick-or-treating on Halloween, a sergeant said today.

A man, his wife and their 9-year-old child were about to leave when someone knocked on the front door of their home in the 500 block of Vernon Avenue in San Jacinto, Riverside County Sheriff's Sgt. Wallace Clear.

When the woman answered the door, three men forced their way in and ransacked the home before leaving with an unspecified number of items, Clear said. Neither the woman nor the child were harmed during the siege that was reported at 4:04 p.m. but the man suffered what Clear described as minor injuries.

The suspects were described as Latinos who wore dark clothing and hoodies that partially covered their faces, Clear said.
