No One Would Tell (2018)

Apparently, the Lifetime movie is indeed based on a true story. It follows the real-life account of 16-year-old high-school student Jamie Fuller, who murdered his 14-year-old girlfriend Amy Carnevale. Fuller was very possessive and abusive towards Amy, and he didn't take it well when she broke up with him. Fuller lured Carnevale to spend time with him and his friends in the woods; when Fuller and Carnevale were alone together in the woods, he reportedly stabbed her 10 times and slashed her throat. Carnevale was murdered on August 23, 1991, in Beverly, Massachusetts.
