(Reuters) - The body of a fourth victim was found on Tuesday in the rubble of an Oakland, California residential building destroyed by a fast-moving fire, the local sheriff's office said.
The unidentified remains were being brought to the coroner's office, the Alameda County Sheriff's Office said on Twitter.
Authorities said on Monday that three people were killed in the blaze and a fourth person was missing.
Only one of the casualties has so far been identified, as 64-year-old Edwarn Anderson.
Firefighters rescued at least seven people from the blaze, the San Francisco Chronicle reported. The newspaper said the building on San Pablo Avenue was leased by agencies running housing and social service programs.
The Chronicle, citing city records, said that numerous complaints had been lodged against the building for safety and sanitation problems.
Last December, 36 people were killed when a fire erupted at a dance party at a sprawling, two-story warehouse in Oakland known as the Ghost Ship that had been leased to an artists' collective.
It was the deadliest blaze in the United States since 100 people perished in a 2003 nightclub fire in Rhode Island.
