FORT MYERS, Fla. - Gail Andrews was in court Monday to plead guilty to federal charges, including social security fraud.  She could face up to 15 years in prison when she is sentenced at a later date.

Andrews, 62, was indicted earlier this year after investigators say she continued to cash nearly $74,000 in her mother's social security checks, while her mother's body decomposed in the Ft. Myers home they shared.

Gladys Andrews' skeletal remains were found in the home, littered with filth, rats and bugs, in the summer of 2010.  Neighbors had complained of a smell coming from the home for months.  Detectives say there was no evidence of foul play.

Lee County condemned the home after investigators uncovered unlivable conditions inside, but volunteers stepped up to help Andrews repair the house - and her life - by cleaning and renovating with the help of donations.

Volunteers were ultimately unable to complete the project.  Court records show Andrews will be sentenced on January 30, 2012.
