Psychotic Mom Thinks She Can Get Away With Double Murder

Quick Read

A routine welfare check spirals into a gruesome double homicide investigation after a missing grandmother's charred remains are found, exposing a twisted family dynamic fueled by eviction and a prior suspicious death.
Marilyn Gandert's disappearance led to the discovery of her charred body, escalating a missing person case to a double homicide investigation.
Initial suspicions focused on daughter-in-law Alyssa Bickett and grandson Drake due to a recent eviction and a prior suspicious death.
The full truth emerged from Alyssa's roommate, Annie, who detailed a coordinated, premeditated murder by Alyssa, Drake, and herself.

Summary

The episode reconstructs the investigation into the disappearance and murder of 65-year-old Marilyn Gandert. Initially reported as a missing person, Marilyn's charred body was later discovered in a remote location. Detectives quickly focused on her daughter-in-law, Alyssa Bickett, and grandson, Drake, who had recently been evicted from Marilyn's rental property. The investigation revealed a history of domestic disputes and a prior suspicious death of Marilyn's son (Alyssa's husband) by alleged Russian roulette. Drake initially confessed, claiming Marilyn asked him to kill her, but it was Alyssa's roommate, Annie, who ultimately provided a full confession, detailing a premeditated murder involving all three: Annie pinning Marilyn down, Alyssa striking her with a club, and Drake stabbing her multiple times. The trio then burned her body to destroy evidence. All three were charged with homicide and accepted plea deals, with Alyssa receiving 30 years.
This case highlights the complex and often hidden dynamics within families that can escalate to extreme violence, particularly when financial disputes and past traumas intersect. It also demonstrates the critical role of persistent detective work and the unexpected turns an investigation can take, from initial missing person reports to uncovering a coordinated murder plot involving multiple perpetrators.

2Focus on Evicted Daughter-in-Law and Grandson

This eviction was a source of significant tension, and officers had a history of responding to domestic incidents involving Drake, who suffered from schizophrenia.

5Annie's Full Confession and the Murder Plot

Alyssa's roommate, Annie, ultimately provided a detailed confession, revealing a premeditated murder. She described how she, Alyssa, and Drake conspired, with Annie pinning Marilyn down, Alyssa striking her with a club, and Drake stabbing her multiple times. They then transported and burned the body.

Annie's detailed account: 'Alyssa… had brought it up before about killing Marilyn… I got Marilyn and from behind and took her down… Drake got on top of her… she gave the bat thing to Drake and Drake started hitting her. We I think we all took turns after that doing that. Started stabbing her and I seen him like going at it a bunch of times and I grabbed the knife from him. He had already cut her throat.'
