Charles Lee Bergeron Molested Boys, Told Them He Needed Their Semen To Live

In a disgusting ploy to lure young boys in to molest them, Charles Lee Bergeron Sr. told them he "needed their semen to live," prosecutors said.

Bergeron was sentenced Wednesday to 120 years in prison for sexually abusing young boys, said prosecutor Cynthia Guillory, according to the Houston Press.

Bergeron would invite young boys into his home, drug or sedate them, and then perform oral sex on them. One victim, who is now 23, told KPLC-TV that Bergeron gave him alcohol with Somas and Xanax, heavy sedatives.

Another victim, who was 13 at the time, said Bergeron gave him oral sex several times, both at his house and at a Westlake, La. cemetery.

Bergeron, 80, was charged with 12 counts of oral sexual battery, 12 counts of indecent behavior, and one count of sexual battery in December. He pleaded guilty to all charges.

Bergeron was previously convicted of molestation in 2000, and he was already in prison serving a 10-year sentence for failing to register as a sex offender when further victims came forward.

The prosecution called Bergeron the "sickest of the sick," according to the American Press.

Defense attorney Robert Shelton countered with a plea to consider his client's health problems. Bergeron is currently receiving treatment in prison.

Bergeron also addressed Judge Clayton Davis, saying, "Mercy is all I can ask for."

“We’ve heard enough from you," Davis quickly retorted. "You’re not worth the time or the verbiage.

The judge gave Bergeron the maximum sentence, including 84 years for the indecent behavior counts and 15 years for sexual battery in addition to the 120 years for sex crimes. Davis acknowledged the extremity of the sentence but concluded that there was "no basis for giving him anything less," according to Houston Press.
