Axar.az informs, citing WPVI, the victims killed include an adult man and an adult woman, Commissioner Kevin Bethel said.

Three teenagers, between 15 and 17 years old, are among the wounded.

The gunfire erupted around 10:27 p.m. on Lemon Hill Drive at Poplar Drive.

Multiple rounds were fired, Bethel said, and investigators are working to determine if several different weapons were involved.

No one is in custody, Bethel said, and no weapons have been recovered.
