Mary Ann had disapproved of Keri’s relationship with Keller, who was 22 at the time, due to the unhealthy and obsessive nature of their connection. Despite attempts to distance the pair, Keri and Rebecca continued to communicate secretly. Their bond only grew more toxic, and eventually, Keri and Rebecca began to discuss plans to kill Mary Ann, who they saw as an obstacle to their relationship.
The investigation revealed that on the night of the murder, Keri had lured Rebecca to her home, and Rebecca carried out the horrific attack. Initially, Keri tried to blame another classmate, Zein Ahmed, for the crime, but investigators quickly debunked her claims. Both Keri and Rebecca were arrested and later accepted plea deals, avoiding a full trial. Rebecca Keller received a 60-year prison sentence for her role in the murder, while Keri, despite her age, was sentenced to 30 years in prison.

Her son, Scott Murphy, shared how their mother had been concerned about Keri’s relationship, recognizing the troubling path her daughter was on.
