Alexus N. Chester was 17 when she was killed during a party in Pittsburgh’s Hill District on the night of Tuesday, June 11, 2019. The gathering at an Airbnb on McNeil Place was celebrating a graduation and her birthday when gunfire broke out at about 11:30 p.m. Officers responding after a ShotSpotter alert found Alexus on the porch with a gunshot wound; she was taken to a hospital in critical condition and later died. A 20-year-old, Tyrese Smith, was also killed at the scene and a third person suffered minor grazing injuries.

Family described Alexus as largely a homebody and said she had been on the porch and an innocent bystander when the shooting began. She was a junior at the Student Achievement Center and hoped to become a pediatrician. Investigators opened a homicide probe but, in the days after the shooting, had not identified suspects or made arrests; the motive remained unclear.

Did anyone who attended that party or lived nearby see suspicious activity on the night of June 11, 2019?
