No one was injured in the fire and no other buildings were reportedly damaged. The affected building, a residence for the mission president, is about 4000 square feet, located behind the temple and the visitors' center. Some of the residence's frame still stands, blackened by the flames. An adjacent building, a residence planned for the temple's president also under construction, was not damaged as much. Most of it still stands.
A Los Angeles Fire Department House of Worship Task Force, part of the department's counter-terrorism unit, was dispatched to the scene for an arson investigation, but that is the standard response for any fire at a religious site, said Matt Spence of LAFD. It is not known whether electric equipment was at the construction site at the time, and an estimate of the cost of the damage is also not available.There are many news reports of the fire (Los Angeles Times, San Jose Mercury News, LA Weekly, Deseret News, CBS LA, 89.3 KPCC, KSL, BYU Universe), all with virtually the same information. We're glad the damage was mostly limited to the single structure and that no one was hurt.
Here are three videos of the fire available on YouTube.
