OCEANSIDE - An Oceanside mom arrested for having sex with a 16-year-old boy will be sentenced today.

Police say Stephanie Finnerty carried on a yearlong affair with one of her daughter's teenage friends in 2009.

Cops say the boy eventually told his parents.

Finnerty was originally charged with third-degree rape.

The mother of three is set to be sentenced for endangering the welfare of a child.
