Two people were found dead from gunshot wounds in a home in Pleasant Hills on Monday morning, authorities said. 

The Allegheny County Police Department said in a news release that officials were notified of a shooting at a home on Nantucket Drive around 7:30 a.m. First responders arrived at the home and received no response from anyone inside, according to county police.

A SHACOG CIRT unit was then called and entered the home around 9:20 a.m., finding a father and his adult son dead from single gunshot wounds. The victims were identified Monday night as 38-year-old Bradley Dawson and 72-year-old Edgar Dawson.

In a report on Tuesday, the Allegheny County Medical Examiner's Office ruled Edgar Dawson's death a suicide, while Bradley Dawson's death was ruled a homicide. Both men were found shot in the head, according to the coroner. 

Friends and neighbors shaken by the incident gathered outside the home on Monday to comfort one another. That is when Allegheny County homicide detectives and forensic teams moved in.

"Everyone involved in the incident has been identified and there is no danger to the public," Allegheny County police said in the news release. 

Police are investigating. No other information was immediately released. Anyone with information can call the county police tip line at 1-833-ALL-TIPS.

The SHACOG CIRT unit is made up of officers from communities in the South Hills Area Council of Governments.
