KNOWLTON — An argument turned deadly Monday night when a man fatally shot his friend's wife and he later died from a medical emergency after his arrest.

Armond Avitable, 38, of East Stroudsburg, Pennsylvania, had been kicked out of his home after a domestic dispute and contacted Kevin Schilling, who lives in the Columbia section of Knowlton, looking for a place to stay, Warren County Prosecutor James Pfeiffer said.

Schilling drove 10 miles to Avitable's home to pick him up and bring him to the home he shares with his wife, Cheryl Schilling, 58.

At some point, the couple began to argue with Avitable, who became "agitated and aggressive," officials said.

Avitable found a pump action shotgun and fired a shot, forcing the Schillings to retreat to their second-floor bedroom, officials said.

Shots fired

Avitable followed them, opened the door and fired two shots, hitting Cheryl Schilling in the arm and upper left torso.

Pfeiffer said Avitable went to a neighbor's home where the residents were in the yard. Avitable told them Kevin Schilling was "coming for him."

Avitable fired two more times at the Schilling house and then ran away, leaving the gun behind, officials said.

State Police found him at the junction of Routes 80 and 46, saying he struggled before they could arrest him.

Cheryl Schilling was pronounced dead at the home around 8:30 p.m. Her death was ruled a homicide.

While in custody, Avitable suffered a medical emergency and was taken to Lehigh Valley Hospital — Pocono where he was pronounced dead.
