Michael Edward Walls was shot and killed during an attempted home invasion in Phoenix in the early morning of Thursday, August 11, 2016. At about 2:17 a.m., three armed, masked suspects tried to force their way into his residence near 2100 E. Mitchell Drive; Walls was shot as he tried to stop the intrusion and did not survive.

Surveillance footage from the area captured the incident and provided descriptions of the three suspects. One suspect is notable for distinctive tattoos: a sunburst-style tattoo on his right shoulder, a possible tribal band around his bicep, additional ink on his elbow, and tattoos on his left arm. Investigators have repeatedly asked the public for help identifying the men.

No arrests have been publicly announced. Does anyone recognize the tattooed individual or have information that could help identify the three suspects?
