Two 13-year-old boys have been arrested after police say they intentionally started a fire that claimed the life of a California firefighter.

On Tuesday, at around 4:14 p.m., the Porterville Fire Department received a call about a massive fire that erupted at the Porterville Library, a spokesperson for the PFD tells PEOPLE.

Fire Captain Raymond Figueroa, 35, and Firefighter Patrick Jones, 25, initially responded to the scene, which was located adjacent to the fire department.

Figueroa was killed while fighting the blaze and Jones remains unaccounted for, PFD says.

PFD says the large number of books in the library — built in 1953 —contributed to it being a large fire.

The flames engulfed the entire two-story structure, resulting in the collapse of the ceiling.

The library was also not equipped with a sprinkler system, making the flames all the more challenging to contain.

At the time of the incident, the library was open to the public and visitors were evacuated by library staff members and fire personnel.

No other injuries or deaths have been reported.

Immediately after the fire started, the Porterville Police Department received a tip about two “suspicious” young boys running away from the scene, Porterville Police revealed in a statement shared on Facebook.

Police later identified the 13-year-old boys, who are residents of the area, and determined they started the blaze.
