UPDATE:Family members for Mr. Grays have been found.

EARLIER STORY: Authorities are asking for the public's help finding family members of a 73-year-old homeless man who died in Birmingham over the weekend.

Richard Lee Grays was found dead Sunday about 8:31 a.m., said Jefferson County Chief Deputy Coroner Bill Yates. Birmingham police and firefighters responded to the railroad viaduct on 18th Street at Morris Avenue on a report of an unresponsive person.

They arrived to find Grays lying on the pedestrian walkway underneath viaduct on a makeshift pallet of blankets and cardboard. He was discovered someone who often visits the area to assist the homeless.

The cause of Grays' death has not been determined, but Yates said investigators don't suspect foul play. Authorities have not been able to locate Grays' family to notify them of his death.

Yates said the man is believed to have a daughter who he listed as an emergency contact with a local shelter, and possible a son who shares his name. All attempts to find them have failed.

Anyone with information on his family's whereabouts is asked to call the coroner's office at 205-930-3603.
