A woman convicted of killing her husband and their live-in mistress has been sentenced to 60 years in prison.

The Anne Arundel County State's Attorney Office says in a news release that 44-year-old Ann Anastasi was sentenced Tuesday. She entered an Alford plea to two counts of first-degree murder in December.

Prosecutors say in October 2015, police found 40-year-old Anthony Anastasi Jr. fatally shot and 25-year-old Jacqueline Riggs stabbed to death in the basement of the Lothian home they shared with Ann Anastasi.

Prosecutors say the three were in a relationship, but Riggs and Anthony Anastasi moved together into the basement.

Investigators say Ann Anastasi plotted with a 13-year-old girl and the girl's boyfriend, 18-year-old Gabriel Struss, to kill Anthony Anastasi and Riggs. Struss has pleaded guilty to first-degree murder.
