A woman who prosecutors say was in a love triangle with her husband and their live-in mistress 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, Maryland.
Prosecutors say the three were in a relationship, but Riggs and Anthony Anastasi moved together into the basement.
Investigators say Ann Anastasi plotted with her 13-year-old daughter 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.
During their investigation, police found text messages among all three suspects that referenced the killing of two people. According to the charging documents, Struss sent a text message to the teenage girl, telling her not to talk to the police or he would go to jail for life. In another message, the girl discussed taking the "fall" for the killings for Struss.
The 13-year-old girl was charged with two counts of first-degree murder and accessory after the fact. Struss was charged with two counts each of first-degree murder, second-degree murder, conspiracy to commit first-degree murder, conspiracy to commit second-degree murder and the use of a firearm in the commission of a felony crime of violence.
