“Until we get more information, the cause of death is undetermined,” he said. Alvarado’s death hasn’t been classified as a homicide or an accident. “We don’t know. We’re trying to determine the circumstances,” said Detective Donna Cheek of the sheriff’s Homicide Bureau. She didn’t want to release additional details about the case. However, Cheek did say that Alvarado was last seen by relatives on a weekend but wouldn’t say what date. His body, mistaken for a burned mannequin, turned up Feb. 4 on the side of Turnbull Canyon Road, south of Blue Sky Road in Hacienda Heights. How a Norwalk man died, and who set his body on fire and then left it on a winding Hacienda Heights road earlier this year remains a mystery. The county Coroner’s Office could not pinpoint what killed Jose David Alvarado. But the coroner’s report showed the 47-year-old had alcohol and cocaine in his blood, sustained injuries to his face and suffered from heart disease. The report listed coronary artery disease, cocaine and alcohol use and traumatic facial injuries as other conditions contributing but not related to the cause of death. The toxicology test showed significant levels of alcohol and cocaine. However, the amounts were insufficient by themselves to be the cause of death, said Craig Harvey, spokesman for the Coroner’s Office. At 3 a.m., a passing motorist told firefighters there was a fire up the road from their fire station. Firefighters used water and foam to put out what they thought was a burning mannequin and then requested county public works employees to haul the debris away. The next day, the workers took a closer look at the mannequin, saw blood leaking from it and realized it was a charred body. Coroner’s investigators discovered remnants of clothing, a charred shoe and parts of a burned left shoe, according to the report. The body wasn’t clothed, although fragments of burned underwear were found at the left knee. The hair was burned off, the body was burned but no soot was found in the lungs, according to the report. Based on the evidence, the coroner concluded that the burns occurred after death. The tip of Alvarado’s right middle finger had been amputated sometime before. It wasn’t a recent injury.
