A father shot and killed his daughter before killing himself in the backyard of their home on Williamsburg Drive in Fairport, near Rochester.

Fairport Police Chief Sam Farina said John Beilman killed his 27-year-old daughter, Nichole Beilman, and then himself around 5:22 a.m. Wednesday.

Nichole had Rett syndrome and had been confined to a wheelchair her whole life, according to Chief Farina.

Donna Beilman, John’s wife and Nichole’s mother, was inside at the time but she did not hear the gunshots. Police said Donna learned of the situation when police arrived.

Chief Farina said John left a “goodbye” note to Donna. A motive for the murder-suicide is not known at this time.
