PHOENIX (AZFamily) — Ricky Wassenaar was already serving 16 life sentences for his role in an escape attempt and hostage standoff at the Lewis Complex prison in Buckeye in 2004. For the past 20 years, he remained mostly out of the limelight, serving his time.

But in April of this year, Wassenaar attacked three inmates in the Cimarron Unit of the state prison in Tucson, killing them, and sparking a controversy over how he was able to carry out the murders and how he had access to other inmates in the first place.

“I would have killed at least seven. My goal was at least seven,” Wassenaar told True Crime Arizona’s Briana Whitney, in a phone interview. She said he seemed excited to talk about it, bragging that he had provided a service, because the inmates he killed were sex offenders.

According to Wassenaar’s inmate profile, at the end of 2024, he was moved out of maximum security, where he had been for decades, and into close custody, which is a slightly lower level of security.

“He was max custody and then he was put out in close custody, which means he gets to walk among them (other inmates),” said Rodney Carr, who is a former warden in the Arizona prison system.

He left the Arizona Department of Corrections, Rehabilitation and Reentry after Gov. Katie Hobbs hired Ryan Thornell as the new director. Thornell came to Arizona from Maine, where he was deputy commissioner of a prison system a fraction the size of Arizona’s.

“I worked for a lot of directors and not always that I agreed with. But that’s my job. Well, with him it got to the point where I couldn’t,” said Carr.

Carr and another former warden, as well as several correctional officers, reached out to Arizona’s Family Investigates with similar complaints: that the department under Thornell’s leadership was moving maximum security inmates into close custody, where it costs less and requires fewer correctional officers to oversee the inmates.

“Under the way they’re managing maximum security inmates in a closed custody environment, staff are going to get hurt,” said Carr.

In an interview with Arizona’s Family Investigates, Thornell said he is moving inmates out of maximum security. “That is absolutely something we are doing. Just like every other department of corrections across the country must do. It’s a practice and we are doing that here,” said Thornell.

He said 90 to 95% of inmates who are in custody will eventually be released into the community, including those in maximum security. And Thornell said keeping them in maximum security the entire time they are in prison is not good for the community once they are released. He said the effect the isolation of maximum custody has on inmates is real and often negative.

“How can I say that somebody in max custody is OK to release into local Arizona, but they’re not OK to release into a close custody yard that still has fences or razor wire?” he said.

When asked if it was a mistake to take Wassenaar out of maximum custody, Thornell said no, but he couched his answer.

“Hindsight is always 20/20, right? So, knowing what I know today, should we have moved him out of max custody? Yes, we should have. Would I do it knowing the facts that I have at my disposal today? Knowing what he did then? No, I wouldn’t. But the practice was sound. It’s still a sound practice,” he said.

Thornell acknowledged that the number of violent incidents in close custody has increased, but he denied that it was the result of max-custody inmates creating more problems.

“It’s easy for a warden, a former warden, to come forward and say, ‘20 years ago, that’s not how we did it.’ Well, 20 years ago, nobody cared who we were releasing back into the community,” said Thornell.
