Forty-two-year-old Jamie Glenn was identified Friday as the sole victim of an apartment fire last month in the 5100 block of Riverton Avenue, according to the county's coroner office.
The April 22 blaze at the two-story structure was reported at 10:14 a.m. and took 53 firefighters less than half an hour to put it out.
Five units suffered fire and/or smoke damage, said Los Angeles Fire Department spokesman Erik Scott.
Glenn, who lived in the building, was taken to an area hospital where he died about an hour after flames broke out, said coroner spokesman Craig Harvey.
It took nearly two weeks to release the name of the victim, a New York native, because his next of kin resides on the east coast, Harvey said.
"It was somewhat challenging to track them down," he said.
An autopsy is still pending.
Scott said arson investigators ruled the fire's cause to be undetermined, although a smoker did live in the unit where the flames originated.
A canine unit was also brought to the scene, but they did not find any accelerates, he said.
The investigation would remain inactive unless some new information is brought to the attention of arson investigators, Scott said.
