A gunman opened fire at a home in Erie, Pennsylvania, killing at least nine people, according to local law enforcement. Two children are among the victims, the police said, adding that the suspect committed suicide.

The police received a report about a shooting at a residence in the city of Erie in the early evening on Friday, according to the local media. Two women were subsequently found dead outside of the home; the other victims were discovered inside.

The suspect reportedly initially barricaded himself indoors, leading to a standoff with the SWAT teams deployed to the scene, the police department said. A local news media outlet photographer, who was present at the scene, stated that he had heard screams and gunfire at some point during the standoff.

The gunman then took his own life, according to Erie Police Chief Rick Lorah, who said the suspect died from a “self-inflicted gunshot wound.”
