Civil rights activists are calling for a hate crime investigation into the alleged killing of a black teenager by a white man just out of prison.
Michael Adams, 27, stabbed the 17-year-old in the neck at a Circle K convenience store in Peoria, Arizona, in the early hours of Thursday morning, the Peoria Police Department said. The boy died at the hospital from his injuries shortly afterward.
In video obtained by KPNX, Adams' attorney Jacie Cotterell argued in court that the attack was "a failing on the part of the Department of Corrections," and said that despite symptoms of mental illness, "multiple prior felonies and a history of potentially unprovoked dangerous behavior," Adams was released into the community without medication or support.
But civil rights advocates say Al-Amin's killing should be treated as a hate crime.
"Michael Adams walked up to a Black teen, Elijah Al-Amin, as he stood at the soda machine and slit his throat b/c he felt threatened by the music he listened to in his car," Kristen Clark, executive director of the Lawyers' Committee for Civil Rights Under Law, wrote on Twitter.
"We must call this what it is — a hate crime — and demand a thorough investigation at the highest level," the Human Rights Campaign wrote.
Democratic presidential candidate Sen. Cory Booker of New Jersey also called for the crime to be investigated by the Justice Department.
Al-Amin's mother, Serina Rides, told NBC News her son was passionate about music and aspired to be as successful as Jay-Z.
"How can somebody be murdered for something that they loved? I don't understand," Rides said. "No baby deserves this for something that he loves."
Rides added she does not believe that mental illness was a factor in the attack. "I don't believe mental illness has anything to do with it," she said. "He was perfectly aware of what he was doing, and his whereabouts. There's no way."
In an interview with KPNX, the victim's father, Rahim Al-Amin, said, "To follow him behind in a store and stab him? I don't care what mental issues you have. You know right from wrong."
"If you're saying that his music is too loud, you're going to kill him?" Rahim Al-Amin said. "I mean like, if he asked Elijah to turn it down, he would've probably turned it down. That's just who Elijah was. 'Oh my bad.' That's probably what he would've said," he added.
The Arizona Department of Corrections told KPNX that Adams had not been classified as seriously mentally ill, and was provided with contact information for resources in the community after he was released from prison July 2.
"Upon release, he was provided transportation from ASPC-Yuma to Maricopa County, after which he was no longer under the Department’s legal jurisdiction and the Department had no further legal authority over him," Department of Corrections spokesman Bill Lamoreaux said in a statement to KPNX.
"The tragic death is terrible, and Mr. Adams will have to answer for his alleged actions," the spokesman said.
