SALEM – A Swampscott patrolman found Miguel Segura?s stolen car crashed and abandoned outside a Lynn playground, the inside covered with blood, the officer testified in Superior Court Tuesday.?The engine was still running,” Officer Saverio Caruso told the jury about the discovery of the robbery victim?s car on Dec. 22, 2008. “I walked up to make sure no one was inside ? and observed blood on the headrests and large amounts in the back seat.”Caruso was the first police officer to speak with Segura outside a Swampscott residence he fled to after being kidnapped, beaten and robbed, allegedly by two Lynn men he claimed to know.Brian Rivera, 23, and Luis Espinosa, 31, of Lynn, are on trial on charges of armed assault to murder, armed robbery, carjacking, kidnapping, and assault and battery with a dangerous weapon in connection with the incident.Segura, 34, testified Monday that the suspects flagged him down for a ride, and then robbed, threatened and beat him in the head with a gun before he managed to exit the car on Foster Road and run to a nearby house as Espinosa shot at him.The pair then fled in his car, which was found by Caruso soon after he first spoke with Segura, whom he said was obviously injured and visibly shaken. Caruso came upon the Acura MDX, which belonged to Segura?s wife, in front of the Clark Street Playground at the corner of Pacific and Boylston streets in Lynn, a short distance from Foster Road.Cecilia Bloom, who lives adjacent to the playground, testified she heard a loud bang outside her window on the night of the incident and looked to see two “dark” men fleeing the vehicle.?I saw them jump out of the car, say, ?Hurry up, we gotta go,? and head up Pacific Street,” Bloom testified Tuesday.She described both men as either black or Hispanic, but “definitely not white.”Foster Road resident Nino DiPietro told jurors he was up wrapping Christmas presents when he heard what sounded like people arguing in front of his house. When he went to a window, he saw a man in the street firing a gun in the direction of Swampscott.After the car left, he said, he saw a man in a white shirt run from the opposite direction to retrieve his jacket. Segura testified Monday he went back to the scene to retrieve his jacket after the assailants drove off, and also that he saw Espinosa firing the gun in his direction. Both witnesses said they could not clearly see the faces of either man.Defense attorneys claim their clients were arrested because of a case of mistaken identity and questioned the Swampscott officer about whether or not Segura implicated the men during his first interview with police.?(Segura) didn?t say, ?Brian Rivera did this to me and he lives at Quincy Terrace in Lynn??” Rivera?s attorney, Mark Schmidt of Salem, asked Caruso during cross-examination.?No, he didn?t,” Caruso said.But Caruso also told Espinosa?s attorney, Kirk Bransfield of Lynn, Segura did say during his initial interview with police that he knew one of the assailants “from the neighborhood,” but he did not claim to know the second man.Segura identified Rivera and Espinosa using photo arrays provided by Lynn and Swampscott Police days after the crime took place, he testified Monday, and said he knew Rivera as a former neighbor and had seen Espinosa at Rivera?s home “a couple of times.”State Police Crime Laboratory analyst Sherri Anderson told Assistant District Attorney Kim Faitella DNA extracted from a soda bottle found in the backseat of the Acura did not belong to Rivera, Espinosa or Segura, nor was any other DNA from the suspects recovered from the vehicle.The trial is expected to go to the jury by the end of the week, Superior Court Judge Howard Whitehead told the jury.Taylor Provost can be reached at [email protected].
