Firefighters from Milford Fire Department and Westfall Township Fire Department in responded to the alarm being raised in April last year at the home of 67-year-old Margie Finlay.

Crews finally entered once they were able to extinguish the flames and found Margie’s body in the kitchen. Milford Police and Pike County Sheriff Office deputies arrested Sisco, 29 for a number of crimes.

Sisco later admitted to police he killed his grandmother and started a fire in the house and blamed his grandmother for putting flea medication on the cat which he claimed was harmful. He is said to have told officers: “She was the devil and I had to do it.”

Local reports said he read scripture aloud as her body was burning on the kitchen floor. He pleaded guilty but mentally ill to the crimes of third degree murder, arson and making terrorist threats. An autopsy determined the cause of death as both sharp force and blunt force injuries.

She had been beaten and stabbed to death before she was set on fire. Sisco had slashed his grandmother's throat and stabbed her before using a kitchen rag to set her on fire, according to local outlets.

Sisco is said to have told local cops that the BIble said "in order to kill the devil, he must use the holy spirit and fire." Prosecutors said: "Sisco admitted to police he killed his grandmother and started a fire in the house, saying the flea medication she was putting on the cat was harmful.”

Pike County President Judge Gregory H. Chelak sentenced Sisco to a total sentence of 23-and-a-half years up to 60 years in a state correctional facility, along with a fine of $2,500 (£1,800). He had pleaded guilty but mentally ill to third-degree murder, arson and terroristic threats in the April 2024 death of his grandma.

A psychological exam originally deemed Sisco, who was diagnosed with schizophrenia, incompetent to stand trial, but a second one cleared him. Margie's son said his mother loved Sisco before calling him a monster. Sisco's lawyer argued his client lost his way when he stopped taking his medication.

District Attorney Ray Tonkin, who prosecuted the case, said “There are no winners here, the loved ones of Margie Finlay deeply grieve their loss and that can never be fully repaired. “The brave firefighters who responded to the scene did their best to save Ms. Finlay, but she was already deceased before the fire was started.

“The responding firefighters, Milford Police Officers and deputy sheriffs did an excellent job performing their duties to save others from more injury and apprehending George Sisco. The Pennsylvania State Police then followed up with their investigation leading to criminal charges.”
