The sister of the Iraq War veteran charged with killing a former Navy SEAL sniper and his friend told a North Texas 911 operator that her brother was "psychotic."
Midlothian police released the 911 call Tuesday. In it, Eddie Ray Routh's sister says her brother came to her house Sunday and told her that he killed two people at a shooting range.
The woman, Laura Blevins, told the 911 operator that she wasn't sure if her brother was being honest with her, but that she was scared he may return to the house.
"My brother just came by here ... he told me that he's committed a murder. I'm terrified for my life because I don't know if he's going to come back here," Blevins said.
In a written statement to police, Blevins wrote that her brother was "out of his mind, saying people were sucking his soul and that he could smell the pigs. He said he was going to get their souls before they took his."
The sister's statement was quoted by a Texas Ranger to obtain a search warrant for Routh's Lancaster home.
Routh is charged with gunning down former Navy SEAL sniper Chris Kyle and his friend Chad Littlefield at a gun range Saturday.
Routh's brother-in-law told the 911 operator that Routh was recently diagnosed with post-traumatic stress disorder and was released from a mental hospital about a week ago.
His actual mental health condition remains unclear and while Routh has been charged in the killing, he has not yet entered a plea. Routh is jailed in Erath County on $3 million bail.
Meanwhile, Kyle's family announced details of his memorial service.
It will be Monday at 1 p.m. at Cowboys Stadium, the family said in a post on his Facebook page.
