At least five people were killed late Wednesday in a mass shooting in suburban Pittsburgh, Pennsylvania, police said, adding that at least two gunmen were involved in the incident. Authorities reportedly said that the suspects are still at large.
Allegheny County police said in a statement that four women and a man were killed during the shooting at a party in the Borough of Wilkinsburg. Neighbors told local media KDKA that they heard at least 25 gun shots.
Lt. Andrew Schurman of the Allegheny County homicide unit told the Associated Press that the gunmen stormed the party and opened fire in an ambush-style attack.
"The ballistic evidence on the scene leads police to believe that two different weapons were discharged from two different people," Allegheny County police said, in the statement, adding that an investigation is underway into the incident.
At least three people were injured in the shooting and are being treated at hospitals, police said, adding that two of them are in a critical condition.
