Brian Mulligan, spokesman for the North Shore-LIJ Health System, which includes Huntington Hospital, said, "We're concerned and hope that he's okay and safely returned. We hope that the police find him and he's brought back to his family and to the hospital. It's shocking and we're just hoping for his safe return."

Police are still patroling the beaches on Thursday. Officers have gone into the woods with quads. 

Gurney said they've been able to conduct searches with the staffing on duty. 

Richardson, whose photograph is attached here, is described as a white man, 5-foot-six-inches tall, 150 pounds, has short gray hair and wears reading glasses. He was last seen wearing running shoes and an orange hat. He has a small scar on his chin.
