ALFRED, N.Y. -- Calling hours for New York State Trooper Nicholas Clark, who was killed Monday in the town of Erwin while responding to a domestic call, were held Saturday afternoon at the James A. McLane Physical Education Center at Alfred University, where Clark attended.

Clark was 29 years old, and joined the state police force in 2015.

His uncle says Clark's family is still trying to process what happened. He was known as a star athlete most of his life, especially here at Alfred University, where his outstanding talent at football got him a tryout for the Buffalo Bills.

After that, he decided to get into law enforcement. Major Richard Allen, Clark’s troop commander, says Clark was an all-around wonderful person, and they've truly lost one of their best. 

"I was up with the family yesterday while they hand dug Nick’s grave and just to see the community support come out for him and stories that were being told, he’s just a great guy," said Allen.

The suspect was identified by officials as Steven Kiley, 43, who worked as school principal in the Bradford Central School District. Police said the dispute was between Kiley and his estranged wife. 

An autopsy report showed that Clark was killed by buckshot from a 12-gauge shotgun, and that Kiley died of a self-inflicted gunshot wound to the head. Officials say he was also shot by police in the chest and would have likely died from his injuries if he had not taken his own life. 

State police investigators found 12 illegal firearms in Kiley's home, including 8 assault rifles. Numerous high-capacity magazines were also recovered.
