New Haven police responded to Lander Street and Winchester Avenue after the city’s Shotspotter system reported gunfire just before 1am Saturday.
Officers discovered several bullet shell casings and a trail of blood leading to a residence on Lander Street.
They found an 18-year-old woman suffering from a gunshot wound to the leg, in the home with other people. Authorities say the woman was attending a party when she was hit by a bullet.
No one at that party is suspected of firing the shots.
The woman, who’s name has not been released, was treated and released from the hospital.
New Haven police continue to investigate.
