A person was found dead inside a Los Angeles apartment building after an explosion that investigators suspect was sparked by fireworks or “homemade explosives,” police said. The blast ripped through the complex in suburban Bell Gardens Tuesday night, leaving a child and an adult injured and displacing multiple families.

Two brothers were killed in an explosion and fire at a Bell Gardens apartment that remained under investigation by bomb squad members, family members said.

The individual's identity was not immediately released, but family members who spoke with Eyewitness News at the scene on Wednesday said the victim was a 13-year-old boy.
