Brenner Justin Anderson, 18, was fatally shot in Glendale, Arizona, on Wednesday, June 29, 2016, in what police described as a robbery. The shooting happened at an apartment complex near 43rd Avenue and Lamar. A friend drove Anderson to a local hospital after the shooting, but he died of his injuries.

Investigators say the meeting that led to the shooting was arranged through social media as a marijuana sale. The friend told police the buyer was a young woman who arrived with two others, and the robbery attempt occurred during that encounter. Glendale police used social media to identify and locate three suspects. On Friday, July 1, 2016, authorities arrested 18-year-old Salem Ornelas, 18-year-old Talmontrai Taylor, and an unidentified 17-year-old female; all three were charged with felony murder in connection with Anderson’s death.

Does anyone have information about the meeting or the people involved that could help clarify what happened that night?
