According to witnesses, a loud crack was heard as the tree fell.

“We just heard something crack, like, really hard, and people were yelling,” Witness Anahi Vazquez told KTLA.

Photographer Gilbert Duran was taking pictures of a quinceañera (fifteenth birthday) party near the tree just moments earlier. 

“We walk away and five minutes later this thing collapses on a whole wedding party,” he said according to news.com.au.

“I just seen a bunch of kids, little kids … they were running for their life and this thing just fell on top of them. I watched them go flat.”

The Los Angeles County Fire Department used chainsaws to pull the tree apart and help rescue people from under its branches. Witnesses performed CPR on the injured. 

“This is an ongoing investigation and it is unknown at this time as to what may have caused the tree to fall,” the police statement said.

The cause of the tree’s collapse is yet to be confirmed. The park has been closed for investigation.
