BRENTWOOD, N.H. — A New Hampshire woman convicted of abusing twin toddlers, leaving one of them blind in one eye, has been sentenced to 20 to 40 years in prison.

A jury has convicted 29-year-old Jami Castine, of Epping, of first-degree assault and second-degree assault charges.

WMUR-TV reports the toddlers' mother says Friday Castine is "the woman who tore my family apart."

Prosecutors say Castine volunteered to watch the 18-month-old twin boys between March 31 and April 8, 2016.

Prosecutors say one child was left with brain damage and permanent blindness in his left eye. His brother had bruises that an expert says were consistent with abuse.

Castine didn't address the court. Her lawyer asked for a shorter sentence, saying she was sexually abused as a teenager and is borderline developmentally disabled.
