BRIGHTON, N.Y. — An incident at a Brighton group home that seriously injured a 69-year-old wheelchair-bound man has sparked an investigation.

Investigators say on November 27, they were called to the Twelve Corners Day Program run by Heritage Christian Services.

Police say Charlie Leavens fell down the stairs and suffered significant injuries, including a broken neck that left him paralyzed. 

Strong Memorial Hospital says Leavens is in guarded condition.

Brighton Police Chief Mark Henderson says staff members were cooperative. 

He believes it does not appear there was any wrongdoing.

"You have our assurance that if it's a criminal act, we will take criminal action. If it's deemed to be an accident, perhaps there are some things that come out of this tragedy and some things that can change. We take care of our most vulnerable," said Henderson.

Heritage Christian Services says they've known Leavens for more than 20 years.

They say he loves volunteering, music and attending church.

In a statement, Heritage said in part: "Although our investigation is ongoing, we have reason to believe that this was an unfortunate accident. It's our top priority to determine what happened and learn from it."

The New York Justice Center for the Protection of People with Special Needs and Monroe County District Attorney’s Office are also investigating.

In a statement, the Justice Center told us in part, “We are currently working with the Brighton Police Department on the investigation into this incident.  Justice Center investigators will also conduct an administrative investigation into this case.”
