A Rhode Island woman will spend life in prison for the part she played in a New Year’s Day murder.
Shaylyn Moran, 20, pleaded guilty to first-degree murder, carrying a pistol without a license and conspiracy to commit murder, and a Providence County Superior Court judge handed down the sentence plus two additional 10-year consecutive sentences on Aug. 5 for the weapons and conspiracy charges.
According to prosecutors, Moran developed a long-distance relationship with her co-defendant, Jack Doherty. Before the couple met in person, the two communicated over the phone and via social media and allegedly conspired to attack Moran’s ex-boyfriend.
On New Year’s Eve, 2019, Doherty traveled from his home in New York to visit Moran for the first time in Rhode Island. He brought with him a 9mm pistol, prosecutors said, and the two went out to a party.
That same night, Doherty proposed to Moran and the two returned to a hotel room they had rented, where they allegedly hatched their plan to shoot and kill anyone who answered the door at the home of Moran’s ex-boyfriend.
On the evening of Jan. 1, 2020, Doherty went to the ex-boyfriend’s home, knocked and when Cheryl Smith answered, he shot her four times, murdering her, prosecutors alleged.
The couple was arrested and taken into custody hours later.
