Two people have died and as many as 11 people were injured after being shot at a party in the East Allegheny neighborhood of Pittsburgh, the Pittsburgh Public Safety Department said in a series of tweets on Sunday.
As many as 10 gunshot victims are being treated at area hospitals, the authorities had said, before updating that an eleventh gunshot victim connected to the incident showed up at a local hospital and that the person's condition was not known.
The authorities' investigation revealed as many as 50 rounds were fired inside a short-term rental property where nearly 200 people had gathered at a large party, according to a statement.
The gunfire prompted some party-goers to jump out of windows, sustaining injuries such as broken bones and lacerations, the authorities said, adding that several more shots were fired outside the home.
The authorities did not release any details about the suspects for the incident.
