A California inmate serving a life sentence for murder confessed in a letter that he beat to death two child molesters with another inmate’s cane hours after a prison counselor ignored his urgent warning that he might become violent.

In a letter to the Bay Area News Group, Jonathan Watson, 41, said he clubbed both men in the head on Jan. 16 at the California Substance Abuse Treatment Facility and State Prison in the small central California city of Corcoran.

The first attack occurred after Watson became enraged that one of the sex offenders was watching a children’s television show, the East Bay Times reported Thursday.

Prisoner David Bobb, 48, died that day. Graham De Luis-Conti, 62, died three days later at a hospital. Both were serving life sentences for aggravated sexual assault of a child under 14.

Watson, who is serving a life sentence for a 2009 murder conviction, wrote that six days after he arrived at the prison, a child molester moved into the pod. Watson believed the man began taunting other inmates by watching children’s television programming.

“I could not sleep having not done what every instinct told me I should’ve done right then and there, so I packed all of my things because I knew one way or another the situation would be resolved the following day,” he wrote.

Two hours before the attacks the next day, Watson told a prison counselor that he urgently needed to be transferred back to higher-level security “before I really (expletive) one of these dudes up,” but the counselor “scoffed and dismissed” him, the letter says.

Watson said he returned to his housing pod.

“I was mulling it all over when along came Molester #1 and he put his TV right on PBS Kids again,” he wrote, according to the newspaper chain. “But this time, someone else said something to the effect of ‘Is this guy really going to watch this right in front of us?’ and I recall saying, ‘I got this.’ And I picked up the cane and went to work on him.”

Watson said he then left the housing pod to find a guard and turn himself in, but on the way, he saw “a known child trafficker, and I figured I’d just do everybody a favor,” Watson wrote. “In for a penny, in for a pound.”
