The Alameda County Coroner's Office has identified the San Leandro man who died Wednesday as a result of injuries sustained during the blaze that destroyed his home at 13115 Neptune Drive.
Dennis Rosucci, 65, was found alive in his bed and was taken to the hospital, where he died.
No cause of death was released. How the fire started remains under investigation.
Former Mayor Tony Santos got to know Rosucci through their work together on a committee to monitor noise at Oakland Airport.
"He was a reclusive guy," Santos said.
Santos said when they met in the late 1990s Rosucci was a day trader.
After the stock market crashed he took another job, Santos said. But the former mayor thinks Rosucci got back into day trading over the last year or so, because he emailed him with stock tips.
Santos said Rosucci was a Navy veteran from the late 1960s.
The one-bedroom home which Rosucci had rented for well over a decade was gutted by the fire that claimed his life, as these pictures show.
