On the evening of June 12, 2016, 31-year-old Angela Linner was in a parked car in Phoenix with her partner, Stefanie Ellis, and Stefanie’s 12-year-old daughter, Maleah. A gunman approached the passenger side and opened fire, firing as many as eight shots into the vehicle. Angela and Maleah died at the scene; Stefanie was critically injured and later died in hospital weeks afterward.

Investigators found no sign of robbery — purses and a significant amount of cash remained inside the car — and the attack appeared random. Police later linked this shooting to a series of similar drive-by attacks that killed nine people across about a dozen shootings in the Phoenix area between August 2015 and July 2016, a span that terrorized several neighborhoods.

What details about that night, the victims’ movements just beforehand, or possible witnesses have not been made public?
