A pedophile was allegedly drowned in his Florida prison cell toilet after being beaten by a cellmate, according to a report.

Convicted child molester David Oseas Ramirez, 56, was found dead in his cell in Jacksonville’s Duval County Jail last Tuesday allegedly after being beaten and drowned in the toilet bowl, according to First Coast News.

He was serving life for lewd and lascivious molestation of an 11-year-old girl — with his 2013 jury taking less than 15 minutes to find him guilty, according to Newsweek.

The attack was witnessed by a third inmate and also captured on surveillance camera footage, which has not been released, the station said. A medical examiner will determine the official cause of death.

Cellmate Paul Dixon, 43, was arrested on suspicion of Ramirez’s murder, authorities announced. He was already serving life for a murder committed when he was 17.

“A verbal altercation became physical. The suspect killed the victim in his cell,” the Jacksonville Sheriff’s Office said in a statement.

“A third cell-mate was present and witnessed the murder. The suspect declined to speak with detectives and requested an attorney.”

The killing highlighted how there is “no peace in jail” for convicted child molesters, News4Jax crime and safety analyst Ken Jefferson said.

“They have to constantly watch over their back. They have to hope they can befriend someone to look out for them,” he said.

Jacksonville sheriff’s assistant chief Brian Kee told Action News Jax that the department has not had a similar crime “in recent memory.”

“I mean, I’ve been here almost 23 years. I can’t recall one,” Kee said.
