Still trying to find out details. I know a Cirrus popped their chute. I believe the other was a helicopter. Edit/Update: A cirrus (N122ES) and an R44 helicopter (N7518Q) collided in the pattern. The helicopter went down near some self storage units with all three killed. The cirrus popped the chute and is down in some fields and trees, not sure exactly. Serious injuries. Audio from LiveATC is attached. Warning, it is bad.
