A Somerville man was found guilty of first degree murder Friday for the stabbing death of an Everett woman in 2009, authorities said.
Antonio Marcos Ferreira, 41, was sentenced to life in prison without the eligibility of parole by Middlesex Superior Court Judge Elizabeth Fahey, according to the office of Middlesex District Attorney Gerard T. Leone.
Police found Sheila Dos Santos, 24, at 154 Main St. about 4:30 a.m. Oct. 2, 2009, suffering from what a medical examination would later determine were at least 37 stab wounds. She was pronounced dead at the scene.
Dos Santos and Ferreira were romantically involved, an investigation revealed, but the relationship had ended months earlier, despite Ferreira's desire for the two to get back to together, authorities said.
Ferreira was tied to the crime by surveillance footage that placed his car near the scene as well as Ferriera, according to Leone's office. Investigators searched Ferreira's apartment, where police found a sneaker with stains of Dos Santos's blood. He was arrested a week later in Charlestown.
"This defendant has now been convicted of planning and executing the brutal fatal stabbing of a young woman in a troubling domestic violence case where the defendant attempted to exert power and control over the victim after she choose to end their relationship,” Leone said in a statement. "I commend the jury for their just verdict."
