http://www.huffingtonpost.com/2014/03/11/theresa-riggi-found-dead_n_4942928.html Her episode "Murder of Innocence" was on Demand, so out of curiosity I googled her and found out she died back in 2014 . For those who don't remembered, she had 3 kids, twin boys and a younger daughter. She was paranoid and narcissistic and totally obsessed with never letting the kids out of her sight. She home schooled them, wouldn't let them out to play with other kids, made them wear electronic tracking devices in public which she activated if they got out of her sight, because oh, they were in the midst of an Easter egg hunt, etc. Hubby got fed up with her behavior and divorced her. When her paranoia got worst over having to let him have the kid for 4 hour visitations, he decided to sue for full custody.

She killed all three kids with repeated stab wounds. Blood evidence was she chased them all over the apartment stabbing them over and over. Afterwards she tried to kill herself by stabbing herself, rigging the gas to explode and burn the apartment and finally throwing herself off the balcony. She survived and got 16 years for the three murders.

Not exactly sure how she died, some articles say suicide, some say natural causes. She was pretty hated by other women in the prison who attacked her repeatedly, including shoving her down stairs.

Hard to feel any sympathy for her when I look at the pictures of her kids in the article
