Did a 21-year-old man kill his childhood friend over thousands of dollars she found in a shoe box? Prosecutors say Liam McAtasney killed his friend Sarah Stern, 19, in New Jersey in December 2016 and then sought the help of his roommate, Preston Taylor, to dispose of her body by throwing it over a bridge. Her remains have never been found. Stern wanted the cash she found in her family's storage unit. Prosecutors say McAtasney strangled Stern and took her money.
