SULLIVAN COUNTY, Tenn. -

It's a guilty plea for a Sullivan County, Tennessee woman who was charged with first degree murder.

Rachel Calhoun admitted Monday that she is responsible for beating, then strangling, 73-year-old Johnny Shankel in February 2011.  Shankel was her next-door neighbor.

Detectives say Calhoun took Shankel's credit cards and $25 in cash.

Calhoun now faces a life sentence, which would make her eligible for parole in 51 years.
