LOS ANGELES (AP) — Authorities have identified a charred body found on Mount Wilson northeast of Los Angeles, where crews working in steep terrain are trying to surround a smoldering wildfire.

Police and coroner's officials on Wednesday identified the man as 18-year-old Matthew Huerta, who was reported as missing and possibly suicidal by his family Oct. 18. Huerta's body was found later that day in a burned area south of the Mount Wilson Observatory.

Officials say it isn't clear if the fire caused his death. An autopsy is planned.

Firefighters are making slow but steady progress against the blaze that broke out Oct. 17 near the 5,710-foot (1,740-meter) peak. It had burned 50 acres of brush and timber and was 70 percent contained by Wednesday.

The cause of the fire is under investigation.
