LOS ANGELES (AP) — A double amputee man armed with a knife and suspected of stabbing a bystander experienced a mental breakdown hours before he was shot 11 times by Southern California police last month, his mother said in an exclusive interview.

Dorothy Lowe said her son, Anthony Lowe, woke up on the morning of January 26 «shaken and frustrated» by the loss of both legs, which were amputated last year. He was scheduled to receive his prosthetic legs on Monday, but he was experiencing more depressive episodes that made her worry that he might hurt himself.

“That morning I felt something,” he said. “She woke up a little rough, I asked him if she was okay and he said, ‘Yeah, I just need some air.’ I offered to take him out, but he wanted to go out alone.

Dorothy Lowe said she called police around 10 a.m. and the responding officers spent about 30 minutes speaking with Anthony in his driveway. One of the officers, whom she did not identify, assured her that Anthony was down on his legs and just needed some fresh air.

“I never knew what they told him, but he came back excited,” Dorothy said of her son. «Then he walked away and I never saw him again.»

Anthony was killed shortly after 3:40 p.m. that same day.

Huntington Park police declined to comment, citing a pending investigation by the Los Angeles County Sheriff’s Department. A spokesperson for the sheriff’s department did not immediately respond to a request for comment.

On Monday, Huntington Park police released audio and video of the moments leading up to Lowe’s death, including video of the stabbing that led up to the encounter, a 911 call from the stabbing victim and related police radio traffic.

“First of all, I want to extend my condolences to the family of Anthony Lowe. I empathize with his pain and understand his demand for information, answers and justice,” Police Chief Cosme Lozano told reporters. «I also understand the local and national clamor for information, transparency and accountability.»

In the first security video, which does not include audio, Lowe sits in a wheelchair outside a Shell gas station in Huntington Park, a city of 53,000 south of downtown Los Angeles. The video shows an unidentified man crossing the street towards Lowe, who appears to briefly follow the passerby and suddenly lunges at him from behind.

The unidentified man is out of sight as Lowe rolls around in his wheelchair.

In another 911 call, the man, who has been identified only as Ramiro, tells an operator that someone with no feet had stabbed him through the heart.

In the second video, recorded at a nearby location, Lowe is seen a few blocks from the gas station in a confrontation with police. An officer appears to pull him out of his wheelchair and onto the sidewalk. Lowe stands on his lower limbs and begins to walk away from him. The police walk behind Lowe, who turns to them and gestures over his head as he holds a large knife. The police continue to follow him and then shoot him. He collapses to the ground before the video cuts out.

In an earlier statement, police said officers first attempted to taser Lowe, but he ignored «verbal commands and threatened to either advance or throw the knife at officers.»

His death sparked outrage throughout the Los Angeles region and called into question officers’ use of force against a disabled person. Several protests and marches have been held since Lowe died on January 26.

«I felt good because there are other people who care, who see something wrong with this, because it was wrong,» said Ebonique Simon, the mother of Lowe’s 15-year-old son.

The officers who shot him have been placed on paid administrative leave pending the sheriff’s investigation.

The Los Angeles County District Attorney’s Office will ultimately decide whether to prosecute them.

“This matter is currently being investigated by the Los Angeles County Sheriff’s Department and has not been submitted to our Office for review,” the district attorney’s office said in an emailed statement. “We cannot control the speed of the sheriff’s investigation, but in light of today’s video release, we are hopeful it will move quickly. We understand and share the public’s concern over the murder of Anthony Lowe.»

Annee Della Donna, an attorney representing several of Lowe’s family members, said police must be held accountable for forcibly targeting a disabled person in the midst of depression.

«There was absolutely no reason to shoot a double amputee limping away from the officers 11 times in the back,» Della Donna said. «Both the officers and the public were not threatened. He was a disabled person suffering from a mental breakdown.»
