An embalmer at a Texas funeral home allegedly cut off a dead man’s penis and stuffed it in his mouth after learning he was a registered sex offender, cops said.

Amber Laudermilk, 34, is accused of taking a scalpel to 58-year-old Charles Roy Rodriguez’s groin while she was overseeing the convicted sex perp’s body at the Memorial Mortuary & Crematory in Houston last month.

Laudermilk carried out the alleged mutilation in front of an embalming student, authorities said.

She allegedly stabbed him twice before castrating him and shoving the remains down his throat, according to police.
