A babysitter who wanted to gain access to young special needs children so that her pedophile boyfriend could abuse them has been sentenced to 100 years in prison.

Brittney Lyon, 31, procured at least four young girls, two aged three and two aged seven, for her partner Samuel Cabrera, 31, to molest while she participated in 2016.

San Diego County District Attorney Summer Stephan released a statement about the horrific case on Thursday, saying Lyon had been sentenced to 100 years or life in jail.

Stephan said that two of the girls had an autism diagnosis, and one was non-verbal. She slammed Lyon's abuse as 'despicable' and 'ruthless'.

Lyon, of San Marcos, California, pleaded guilty in May to two felony counts of lewd act upon a child and two counts of forcible lewd act upon a child.
