A jury found 18-year-old Mathew Borges of Lawrence, Massachusetts, guilty of first-degree murder for the 2016 killing of then-16-year-old Lee Manuel Villoria-Paulino.
“Nothing can bring Lee Paulino back to his family, who obviously love and miss him very much,” Essex County District Attorney Jonathan Blodgett said in a statement Tuesday.
In his closing arguments Monday, Assistant District Attorney Jay Gubitose said that Borges had the means, motive, and opportunity to kill Paulino.
The prosecution argued that Borges was jealous because Paulino had spent time with his girlfriend.
Prosecutors said Borges distracted Paulino to get him out of his house while other teens robbed it, and then killed him.
CNN affiliate WCVB reported that medical examiners found 76 wounds on Paulino’s body – and that they were unable to determine whether particular wounds, including his beheading, took place before or after his death.
Since Borges was a minor when Paulino was murdered, he faces a life sentence with the possibility of parole, according to the Essex District Attorney’s office.
Borges is scheduled to be sentenced on July 9.
