SOUTH STRABANE TOWNSHIP (KDKA) — A double stabbing in South Strabane Township sent two people to the hospital over the weekend and landed a man back in jail.

David Vaughan, 55, of Washington, Pennsylvania, is facing two counts of attempted criminal homicide, as well as charges of aggravated assault and terroristic threats.

The South Strabane Township Police Department said Cathy Ringer, the suspect’s girlfriend, called 911 just before 5 a.m. Saturday, sending police to the East Maiden Street home.

According to the criminal complaint, Vaughan had been out with Ringer and Ringer’s cousin, Harry, the evening before. The three returned home and began drinking alcohol together.

Cathy Ringer told investigators that she went to bed around 9:45 p.m. and later awoke to “the sound of loud banging” and arguing.

Police say she went downstairs to find several items were knocked over, making it “apparent that a struggle or fight had occurred in the living room.”

The two men, according to the criminal complaint, then got into another fight in the kitchen. Cathy Ringer said she could hear Harry saying, “He’s stabbing me.”

He suffered multiple stab wounds to the chest.

Police say Cathy tried to pull Vaughan off of Harry, and that’s when she stabbed in her forearm. She also suffered a severe laceration to her foot.

Investigators say she told them that Vaughan said during the alleged attack, “You know I have to kill you both. I have to finish this and kill you.”

She was able to get away and call police. Officers found her attending to Harry when they arrived. He was taken by medical helicopter to UPMC Presbyterian Hospital for treatment. Police say his injuries are life-threatening.

Cathy Ringer is expected to be okay. She declined to talk to KDKA and said she is “still trying to process it all.”

Police found Vaughan about an hour and a half after the stabbing hiding near another home. They say he had blood on his clothing.

Police said after his arrest Vaughan told them he had recently gotten out of jail after serving a 10 year sentence for domestic violence.
