The Tempe Police Department published body-scan footage of the incident.
The officer, identified only as Jaen, responded to a call from a citizen who reported a suspicious vehicle and approached a gray Chevy pickup, apparently involved in a parked burglary. In an alley, the Tempe police chief said in a press conference ,
The video shows the officer taking cover behind a trash can while the teenager is leaving the truck. You can hear the officer calling for the teenager to raise his hands while running away from Jaen.
"He has a handgun," says Jaen on the footage.
The weapon was a replica of the 1911 Airsoft gun that the teenager had just stolen from the truck, Moir said. She said he had other stolen items with him.
The teenager almost runs to the end of the alley, and the officer shoots two shots.
One of the shots hit him with his shoulder blade and the other hit a wall at the end of the alley, Moir said. The authorities did not report a cause of death.
"We're trying to figure out what happened, the video is just one part," said Danny Ortega.
The family went to the police station and asked to see the material. Ortega said the distance between the officer and the boy when he was shot seemed considerable.
"It was a long distance, so how could this young man pose a threat at this distance is a question that must be asked." asked.
Officer Jaen has been in Tempe police for 14 years and was in the National Guard from 2007 to 2013. Moir said he served in Iraq in 2011
Administrative leave has been transferred before criminal and administrative investigations are pending.
Moir said the department is focused on "open, honest and empathetic" but "encourages everyone to withhold the sentence until the criminal and administrative investigations are completed.
The mayor of Tempe, Mark Mitchell, said he was going to mourn the family son he identified as Antonio Arce.
"All young people have the promise of making a meaningful Le ben and to contribute to a greater good, "said Mitchell. "If this potential is interrupted for any reason, this is a tragedy that can not be overstated."
He also showed understanding for the police officers of the Tempe Police Department who have focused on building the trust of the community. He said that funding has been provided for additional training, and he hopes to further develop "understanding, cooperation and trust".
Mitchell also calls for thoughtful discourse and behavior during the ongoing investigation.
"The release of The Body Camera Materials and Officer's Name will be further investigated this afternoon, which is understandable and justified, and I would ask individuals to be patient when we learn the facts," Mitchell said.
