Suffolk County District Attorney Daniel F. Conley today announced the convictions of four men for the murder of 16-year-old Terrance Jacobs in Dorchester almost exactly three years ago.

A Suffolk Superior Court jury found PAUL GOODE (D.O.B. 1/9/83), PEDRO ORTIZ (D.O.B. 8/8/79), and TERRANCE PABON (D.O.B. 1/22/90), all of Dorchester, and MARKEESE MITCHELL (D.O.B. 4/9/91) of Brockton guilty of second-degree murder for beating and stabbing Jacobs to death on May 22, 2007.

“This was a just verdict and one supported by the facts, the evidence, and the law,” Conley said. “For three years they’ve waited for justice, and today it was delivered by a jury of 12 members of the community. It took herculean efforts on the street, in the grand jury, and before the jury, but those efforts paid off.”

Suffolk Superior Court Judge Judith Fabricant will sentence all four defendants tomorrow at 9:00 in courtroom 907. All face a mandatory term of life in prison with the possibility of parole after 15 years.

During four full weeks of testimony, Assistant District Attorney Mark Hallal of Conley’s Senior Trial Unit proved that Goode, Ortiz, Pabon, and Mitchell were, at the time of the murder, friends of a 14-year-old boy whose face Jacobs had slashed with a razor in January 2007.

While that case was heading toward indictment in Suffolk Superior Court, the evidence showed, the defendants made arrangements for some of Jacobs’ friends to bring him to the area of Wilcock Street for what the teen believed to be a one-on-one “beatdown.”

When Jacobs arrived near the intersection of Blue Hill Avenue and Wilcock Street, Hallal said, the defendants and others threw him to the ground and began kicking him. One of Jacobs’ friends pulled a gun and fired a shot into the air, at which point some members of the group dispersed.

Jacobs began to run for his life but was soon chased down by the group. When the attack was over, Jacobs was kicked, beaten, and stabbed 20 times in his chest, back, legs, arms, and hands.

Hallal tried the case with Assistant District Attorney Stacie Moeser of the DA’s Major Felony Bureau. Paula Connor was the victim-witness advocate assigned to the case. Goode, Ortiz, Pabon, and Mitchell are represented by attorneys Scott Curtis, Michael Doolin, Stephen Neyman, and Elliot Weinstein, respectively.
