On December 2, 2016, a fire broke out at an Oakland warehouse known as the Ghost Ship. The warehouse had been converted into an area for artists which included living units.
Alameda County officials announced on June 5, 2017, they have arrested two people in connection with the fire: lanlord Derick Almena along with Max Harris, who has been described as a tenant.
A teenager and a deputy's son were some of the 36 people killed.
Some victims had to be identified through DNA and dental records, he officials said. Officials also worked with the transgender community to identify some of the victims.
The city's district attorney activated a team to launch a criminal investiation.
KRON TV reports investigators believe the fast-moving fire may be started from an electrical problem, although a cause was never determined.
Oakland Battalion Fire Chief Melinda Drayton said firefighters had to remove debris "literally bucket by bucket in a methodical, thoughtful, mindful and compassionate way."
Officials said the roof collapsed onto the second floor before parts of the second floor collapsed on the first floor. After firefighters extinguished the blaze, they said the building so unsafe emergency responders couldn't enter.
The building is known as the "Ghost Ship." To the artists who lived and worked there, the Ghost Ship was a coveted haven in the Bay Area's gentrifying landscape of skyrocketing rents and disappearing artist spaces.
Media reports said the warehouse's owners had received notification of city code violations for hazardous trash and debris, property records show.
