Woman in love triangle admits to killing husband, mistress

A woman who prosecutors say was in a love triangle with her husband and their live-in mistress has pleaded guilty to her role in their slayings.

The Anne Arundel County state's attorney's office said in a statement that 43-year-old Ann Anastasi pleaded guilty to two counts of first-degree murder Wednesday.

On Oct. 5, 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 home they shared with Ann Anastasi in Lothian.

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 pleaded guilty to first-degree murder in June.
