Karina Clark
Karina Clark (c. 1976 - December 7, 2017) was a murderous villainess who orchestrated the murder of her nine-year-old daughter, Madison Clark, in 2017.
Karina's backstory revealed a history of mental illness, including being diagnosed as bipolar. She was reported as being at her happiest with Madison, while it was also uncovered that she was estranged from her other children; however, Karina's depression worsened following gastric bypass surgery.
On December 7, 2017, Karina turned heel and shot Madison to death, firing three fatal gunshots before turning the gun on herself. As revealed, Karina's relationship with her boyfriend at the time ended before her murderous actions, and it was reported that hints of Karina's maniacal heel turn came when she actually stated that she would kill herself and Madison if her boyfriend broke up with her. The bodies of Karina and Madison weren't discovered until New Year's Eve, 24 days after the deaths.
