Alan Scott Jr Hoover, known as AJ, was 16 when he was shot and killed on the evening of Wednesday, January 7, 2015, at a residence near 2300 East Shaw Butte Drive in Phoenix, Arizona. Born May 4, 1998, he was remembered for an infectious laugh and smile and described as competitive and active, with interests in basketball, baseball and hiking.

AJ grew up with four older sisters, spent much of his childhood in Houston, Missouri, and had returned to Phoenix in August 2013. He hoped to finish high school and enlist in the military. The Phoenix Police Department opened a homicide investigation; publicly, the shooter and any other persons present at the time remain unidentified and no arrests have been announced.

Who knew AJ or was in that neighborhood on January 7, 2015, and can help investigators fill in what happened that night?
