Mourners attended a private funeral at the Lincoln Memorial United Methodist Church in Buffalo, New York, Friday for Deacon Heyward Patterson, a 67-year-old who was at the Tops grocery store to pick up supplies for the church’s food kitchen when he became the victim of a hate-filled mass shooting. 

Patterson was one of ten people killed when the gunman rushed in with an AR-15. Three others were wounded.

"His loving memories remain in the hearts of many family and friends," an obituary posted by the Thomas Edward Funeral Home reads. 

Patterson was being buried at St. Matthew’s Cemetery, just a mile and a half from where a gunman took his life in an unprovoked attack.
