CONCORD, N.H. (CBS Connecticut/AP) — A New Hampshire woman has been sentenced to nine to 30 years in state prison after pleading guilty to subjecting her 18-year-old son to beatings and other physical abuse.

Christine Gelineau of Concord reached an agreement with prosecutors, pleading guilty Thursday to first-degree assault and witness tampering.

The Concord Monitor reports assistant county prosecutor George Waldron said the teenager suffered permanent nerve damage in his penis when the 53-year-old Gelineau burned it with a lighter in April.

Gelineau is also accused of burning her son’s nipples completely off, stabbing him with a pen and forcing him to eat worms.

“He was also told that if he did not eat some worms that were provided to him that they were going to burn his penis. He did in fact eat the worms,” prosecutor Tracy Connolly said.

An acquaintance of Gelineau’s, 20-year-old Daniel Tyler Cantrell, faces trial next month on multiple charges associated with the abuse. Cantrell is accused of twisting the 18-year-old’s ankle before it broke and also forcing him to eat feces.

A cousin of the teen, 29-year-old Amy Nason, is scheduled for a plea and sentencing hearing next month.
