Suffolk County, NY — A West Babylon man accused of dragging a 65-year-old amputee from his car, beating him to death, and stealing the victim’s vehicle now faces a murder charge after a months-long investigation tied him to the brutal December 2024 attack in Deer Park.
Suffolk County District Attorney Raymond A. Tierney announced Thursday that 25-year-old Jason Butt-Champagne was indicted on charges including second-degree murder and first-degree robbery in the death of Donald Klune, who died two days after the alleged assault.
Prosecutors say Klune, who had only one leg, was unable to defend himself during the violent robbery on Brook Avenue.

According to the investigation, Klune was sitting inside his parked vehicle around 8:30 p.m. on December 11, 2024, when Butt-Champagne allegedly approached him on Brook Avenue in Deer Park.
Investigators allege Butt-Champagne forcibly pulled Klune from the vehicle before repeatedly kicking and beating him in the roadway. Prosecutors said the suspect then drove away in Klune’s car, leaving the injured victim behind without his phone.

A passerby later discovered Klune lying in the road and called 911.
The 65-year-old was transported to South Shore University Hospital, where he died on December 13, 2024. The Suffolk County Medical Examiner later ruled his death a homicide caused by blunt force injuries.
“This defendant allegedly brutally attacked Donald Klune and left him for dead on the side of the road for nothing more than his car,” District Attorney Tierney said in a statement Thursday. “The Suffolk County Police Department never gave up in our pursuit of justice for Mr. Klune and his loved ones, and my office will continue to do so during this prosecution.”
