"He did not deserve that. He didn't hurt them, he didn't kill nobody. He was scared, running away from the police," said Hollins mother Sarah Coleman.
She and other community activists call for an outside investigation.
"Because we see this all the time. Everyday, and I'm tired of it. I didn't know it was going to be my son next," said Coleman.
Tempe Police say Lieutenant Edward Ouimette was the officer involved and they have spoke with federal investigators concerning the incident.
Authorities say the Lieutenant and Hollins met in the parking lot of a senior center after he fled from the Walgreens. Ouimette was yelling commands, but Hollins didn't comply.
"At which point Hollins turned towards Lt. Ouimette and pointed what Lt. Ouimette believed to be a gun. Lt. Ouimette at that point moved out of the way and fired one round striking Mr Hollins," said Lt. Mike Pooley.
Ouimette fell after shooting at Hollins, by the time he got back up Hollins had fled and was found nearby by a maintenance shed. During the investigation authorities have not found any weapon.
"While a finding like this causes all of us significant concern we will continue to pursue a sound, unbiased, factual investigation," said Chief Sylvia Moir.
