Warren Jeffs, the Fundamentalist Church of Jesus Christ of the Latter Day Saints leader who was convicted on charges of sexually assaulting two underage girls, is near death, an undisclosed source told ABC News. Jeffs is currently serving a life in prison with no possibility of parole for 45 years sentence.

The 55-year-old has been listed in critical condition after he was taken to the East Texas Medical Center in Tyler, Texas Sunday night. Jeffs had reportedly been fasting for three days in his Texas jail cell. The fasting prompted the notoriously creepy leader to fall into a coma, a source said.

Jeffs has not been eating/taking in fluids as he should, prison spokesman Jason Clark said. He indicated he was not on a hunger strike but fasting. The inmate also has other medical conditions that have risen to the level of needing hospitalization, Clark added.

Jeffs has maintained that the two underage girls he assaulted were his brides from spiritual marriages.

Jeffs is scheduled to go on trial again on charges of first-degree bigamy. If convicted, he could face up to 99 years or life in prison in addition to $10,000 in fines.

As people in jail notoriously do not like child predators, Jeffs had been moved to a solitary cell.

Jeffs is described as in critical but stable condition.

He did indicate to staff that he was fasting but he is currently being treated for other medical ailments and conditions, spokeswoman for the Texas Department of Criminal Justice Michelle Lyons told ABC News.

Jeffs maintained that he was being persecuted for his religious beliefs throughout the trial.

Prosecutors played an audio recording of Jeffs sexually assaulting a 12-year-old girl. The audio recordings also revealed a hot-and-bothered Jeffs advising as many as 12 of his young wives on how to sexually please him.

Jeffs had 78 illegal wives, 24 of them underage, prosecutors said.

If the world knew what I was doing, they would hang me from the highest tree, Jeffs said in a 2005 note which was later discovered in his Texas home.
