20/20 on ID examines the case of Liam McATasney, who murdered his old school friend, Sarah Stern, in the hope of stealing her inheritance money.
McAtasney strangled his so-called friend 19-year-old Sarah Stern in her home in Neptune City, NJ, on December 2, 2016. The pair had known each other since grammar school.
He then enlisted the help of his best friend, Preston Taylor, to dispose of the body and stage her death to look like a suicide.
A few hours after her death, McAtasney and Taylor took Sarah’s car and left it by a bridge in nearby Belmar, NJ. They then threw her body over the bridge. Sarah’s body has never been found.
Investigators were left perplexed at Sarah’s disappearance, and the case might have grown cold, were it not for one massive error by McAtasney. He was recorded by another friend admitting to the murder.
Anthony Curry agreed to record McAtasney making the confession with a hidden camera.
Liam McAtasney wanted Sarah Stern’s inheritance money
Investigators concluded that McAtasney’s motive for murder came down to money. He had hoped to steal thousands of dollars that Sarah’s mother had left for her when she died of cancer in 2013.
He had plotted to kill Sarah for six months so he could get his greedy hands on her lockbox, which he believed was stuffed with dollars.
McAtasney was recorded complaining that he hadn’t been able to find as much money as he had hoped. He said: “It took me half an hour to kill her… The worst part of it is I thought I was walking out [with] $50,000 to $100,000 in my pocket. She had one safe that she took money out [of], and she only had $10,000.”
Taylor, who had taken Sarah to the junior prom, would later agree to testify against his friend. At the trial, Judge English said Taylor had “folded faster than anybody I’ve ever seen.”
He pleaded guilty to six charges involving robbery and the treatment of human remains and received a sentence between 10 and 20 years.
McAtasney was sentenced to life in prison without the possibility of parole; he was also given an additional ten years.
