DALLAS -- Dallas police said William Palmer, stabbed his wife and his in-laws to death on Thursday morning
Palmer and his wife Donya Palmer, 47, separated about a week ago according to police. She was staying at her parents’ home in the 2100 block of Peavy Road.
Around 6 a.m. Donya went outside to her car. Palmer was apparently waiting for her. Police said he chased her into the home with a knife in hand.
Police said Donya was stabbed first. Her parents, Raymond and Mary Davis, heard her screams.
“He attacks her and then he begins to stab her,” said Lt. David Pughes, Dallas Police Department. “Her father, who is 69-years-old came out and he was subsequently stabbed also by the suspect. At that time the mother, who is 76-years-old, can out to try and see what the commotion was and she was also stabbed.”
Donya’s sister and niece were also in the home at the time. Palmer stabbed the sister in the arm, but she was able to get away. She grabbed her daughter and ran for safety as Palmer roamed through the house searching for the two survivors.
“She ran to an upstairs bedroom and hid there,” Lt. Pughes said. “Was able to hide in that bedroom and call 911 and direct the police.”
Police arrived within four minutes of that 911 calls, but Palmer had already left the premises.
Palmer drove to his home in Sachse. Undercover agents who were working nearby went to the home and then followed him to a fast-food restaurant where he was arrested after placing his order.
“It’s impossible to provide an explanation of what might be going through someone’s mind or what might cause somebody to snap and commit an act as heinous as this,” Lt Pughes said.
Police said the Palmers have three adult children. Their children were not aware of any domestic violence issues.
