Mom to 911: 'My Children Are Trying to Kill Me' Georgia brothers charged after allegedly drugging and attacking parents By Michael Harthorne, Newser Staff Posted Sep 8, 2015 5:45 PM CDT 85 comments Comments (Shutterstock) (Newser) – Two brothers allegedly tried to kill their drugged parents and burn down their home near Atlanta Saturday morning, and neither their parents nor the police have any idea why, CNN reports. Police say Cameron Ervin, 17, and Christopher Ervin, 22, slipped their parents Xanax to make them sleepy before attacking them. Their father Zachary escaped to the garage and started hitting a car horn to try to get neighbors' attention; his wife Yvonne ran upstairs to hide and call 911. Sgt. Rich Long tells CNN this probably saved their lives. The Atlanta Journal Constitution reports the 911 dispatcher could hear Yvonne listening to her sons coming up the stairs and one of them asking if she was on the phone before dragging her away; she was beaten, and her husband was beaten and stabbed. Police arrived to find Zachary and Yvonne with serious injuries, the Journal Constitution reports. Police say Cameron told an officer, "I tried to kill my [expletive] parents. Who does that?" following his arrest. CNN reports Cameron and Christopher also allegedly filled the Snellville-area house with natural gas in an attempt to burn it down. They've been charged with aggravated assault and arson. Yvonne told the 911 dispatcher maybe her sons were trying to kill her for insurance money, but she wasn't sure. Neither are police. "There is no official motive at this point, but there has to be something more to this," Long tells CNN. "I'm sure they didn't just wake up and decide to kill their parents yesterday."
