The shooting happened on Saturday, March 21st at around 10 p.m. on the 4700 block of Hartnett Ave. just east of Carlson Blvd. and Interstate 580.

Officers who responded to a ShotSpotter gunshot detection system found a 17-year-old gunshot victim at the apartment complex with injuries to his legs that were not considered life-threatening, police said.

The investigation determined that the victim was with a group standing in front of their homes to get some fresh air due to the recently-enacted “shelter in place” public health order.
