Horrifying video shows a janitor in California stabbing a paralyzed man in a violent frenzy

A chilling surveillance video shows a former California nurse stabbing a paralyzed man after he drove a minivan into his home.

The suspect, 47-year-old Aaron Matthew Shindle, was shot by a police officer less than half a mile from the victim's Woodbridge home on August 5. He later died of his injuries.

The video shows the encounter between the police officer and Shindle, who was carrying the same bloody knife that was used to kill 38-year-old John Alexander Bash.

Surveillance footage from the home shows the former caregiver racing a Honda Odyssey into Bash's garage before entering the house.

Shindle then entered the victim's bedroom and stabbed his former patient multiple times.

Bash's current caregiver called 911 after finding the man bleeding and unconscious.

John Alexander Bash, 38, who used a wheelchair to get around, died from stab wounds inflicted by his former caregiver after a break-in on August 5.

The desperate caregiver explained to the emergency services on the phone: “I'm a nurse. A quadriplegic has blood everywhere! It's like a crime scene, I don't know what to do!”

While police were searching the neighborhood for the attacker, an officer noticed a lone man at the intersection of Stonecreek South and West Yale Loop.

Bodycam footage showed an IPD officer confronting the man, repeatedly asking him his name and if he lived in the area before seeing the knife.

As the suspect approached him, the officer repeatedly ordered the man to drop the knife.

During the exchange, Shindle raised the knife and advanced toward the officer, who fired several shots. Shindle was immediately transported to a local hospital, where he later succumbed to his injuries.

When officers found Shindle, he was still holding the murder weapon.

“The male suspect appears[ed] to be the driver of the minivan that crashed into the house, presumably killing the victim,” IPD said in a statement following the incident.

Neighbors who did not witness the incident but were aware of the subsequent police presence spoke to CBS News after the incident.

They revealed that Bash had been in a wheelchair since an accident several years ago in which he jumped headfirst into the shallow waters of Lake Havasu in Arizona. They remembered him as an uplifting presence in the neighborhood.

“He was always really nice to us and I'm just overwhelmed,” said neighbor Marilyn Botzenhardt, who lives just a few meters from the scene of the accident where the murder occurred.

“I can't believe this,” she said of the crime. “Who would do something like that?”

While police continued to search for a motive, IPD Sergeant Karie Davies said there were still no leads.

“As far as we know, there was no argument,” she said, while officials said the IPD would not conduct a separate investigation into the shooting.

“According to the victim's family, this came out of the blue,” she said. “Our investigators will have to find out.”

Tributes to Back poured in on social media, portraying him as an adventurous, resilient man who managed to stay positive after losing his legs in 2015.

“It’s so sad that this happened to Johnny,” wrote Irvine resident Jenée MacBeth.

“He was a nice guy. I hadn't spoken to him since high school. It just breaks my heart that his family had to deal with his accident years ago that left him paralyzed and now this horrific, tragic, violent loss. He grew up here in Irvine.

“What a disgusting act to take the life of a kind, determined and defenceless person,” she added.

“Johnny is such a sweet guy who has been through so much,” said another. “Just awful.”
