Anastasi was charged in October 2015 with murdering her husband and a romantic interest they shared with the help of her 13-year-old daughter and the girl's 18-year-old boyfriend, police said.
Forty-year-old Anthony Joseph Anastasi Jr. and 25-year-old Jacqueline Irene Riggs were found dead Oct. 5, 2015 inside a home in the 600 block of West Bay Front Road in Lothian.
Police said Riggs had been romantically involved with both Anastasis. But when Riggs moved into the basement of the couple's home, it caused tension.
The 18-year-old, Gabriel Struss, pleaded guilty in June to charges including first-degree murder. He was sentenced in August. The 13-year-old was sent to a juvenile detention facility.
