Police have released the 911 audio after an ex-Marine admitted to his sister that he’d killed former Navy SEAL sniper Chris Kyle and his friend Chad Littlefield.

Eddie Ray Routh, the alleged shooter, apparently went to his sister’s house after the killings and told her that he had "traded his soul for a new truck" -- a supposed reference to the one he stole from Kyle. When Routh left, the sister, Laura Blevins, called 911.

Blevins told the operator her brother admitted to a murder and left her house. She said, “I’m terrified for my life.”

The sister described her brother as “psychotic” and eventually handed the phone over to her husband.
