Oxygen Presents 'Killer Grannies'

"Killer Grannies," a new true-crime series on the Oxygen network, hosted by Oscar-nominated actress June Squibb, chronicles shocking cases involving a killer no one would suspect: Grandma.

In every self-contained episode, a rollercoaster ride of a case unfolds as investigators dig deep and chase every lead until they finally catch their unexpected killer.

Through gripping archival footage, selective recreations and cinematic imagery, and in-depth interviews with investigators, prosecutors, friends and family, each episode will peel back the plastic cover on the couch to uncover a world of sinister plots and evil deeds, unpacking why and how these maternal matriarchs of the family can turn deadly.
