In HBO's new series "Murder on Middle Beach," filmmaker Madison Hamburg takes a deep dive into the life and untimely death of his mother, Barbara Beach Hamburg.

Beach Hamburg was found dead outside of her Connecticut home in 2010.

And while her ex-husband Jeffrey Hamburg, the father of her two children Madison and Ali, was initially considered a suspect in her murder, he was never charged, and Beach Hamburg's case remains unsolved.

Throughout the show, Beach Hamburg's son and the series' director Madison Hamburg uncovers several surprising details about his mother's life, including her involvement in a pyramid scheme-like operation for women known as "gifting tables."

He also questions several of his family members about their knowledge of Beach Hamburg's murder, and is eventually able to eliminate some of them as potential suspects in his own investigation.
