A mother can go to any lengths for her child and that’s what Lifetime’s upcoming movie is all about. Titled ‘The Long Island Serial Killer: A Mother’s Hunt for Justice’, the cable network’s upcoming true-crime film chronicles the journey of a woman named Mari Gilbert and her search for the truth behind what happened to her daughter Shannan, a sometime escort who disappeared after a ‘date’ on Long Island.

Based on a true story, the Long Island Serial Killer is an unidentified suspected serial killer who is believed to have murdered 10 to 16 people over a period of nearly 20 years. His victims are mostly prostitutes and the bodies are left in areas on the South Shore of Long Island, New York. One of his victims was Shannan Gilbert, a 24-year-old woman from New Jersey, who was reported missing on May 1, 2010. According to the investigation, Gilbert, who worked as an escort, was last seen running from one of her client’s home in the Oak Beach area.

Police found a body upon searching and ordered a search operation in the entire area. Two days later, police officials found three more bodies in the same area, on the north side of the Ocean Parkway. The law enforcement authorities said that finding four bodies in the same area is “more than a coincidence".

The movie will tell the story of Gilbert’s disappearance, police investigation and her mother’s hunt for the serial killer.

Release date

The 400th original movie from Lifetime, which is a part of the ‘Ripped from the Headlines’ franchise, will exclusively premiere on Saturday, February 20, at 8 pm ET. 

Plot

Based on a true story, the movie covers the Long Island serial killer and how he murdered several women, mainly prostitutes, between 1996 and 2013. It also tells the story of a mother who seeks to find the truth behind her daughter’s disappearance.

The official synopsis reads: “After Shannan (Katharine Isabelle) fails to come home, her mother Mari (Kim Delaney) knows something is terribly wrong. Pleading to the police to take her concerns seriously, she keeps pushing the police for answers. Mari’s insistence that her daughter not be overlooked eventually leads to a horror hidden on Long Island for more than a decade – 19 bodies of young women discovered buried in shallow graves along Ocean Parkway in the area of Jones Beach State Park. Though the search for the killer is still ongoing, Mari’s passionate dedication to giving her daughter and other forgotten women a voice, and the attention they deserve, has kept the case alive with hopes of a breakthrough soon.”

It will be interesting to see how the network uses the source material because Shannan Gilbert’s case is still “unsolved".
