Officials say a deceased male in his 30s — later identified as Jonathan Paul Kulick, 37 — was found inside the home. According to investigators, Kulick did not live there.

A police report released Tuesday concluded that Kulick had fired multiple shots into the rear door of the home in order to gain entry.

Once inside, police say Kulick suffered from one self-inflicted gunshot wound, but multiple shots were fired.

Neighbors on the street say they witnessed and heard police taking at least three people to the station for questioning.

Two women, one man and a juvenile live in the home, according to police.

Police say two people were inside the home where the victim was found.

“There were witnesses. Those people were brought to the local police department and they were questioned just for their statements,” Armstrong County District Attorney Katie Charlton said.

Investigators said no charges will be filed.

“We did retrieve the firearms, and at this point we’re not gonna really say what they were either,” Brian Myers, the Armstrong County coroner, said.

The manner of Kulick’s death has been ruled a suicide, according to a statement released by the Armstrong County Coroner’s Office on Tuesday.
