A Suffolk Superior Court jury this morning convicted a 65-year-old Dorchester woman of manslaughter for stabbing 74-year-old Julius Scott to death in the apartment they shared last year, District Attorney Daniel F. Conley said.

Jurors found VERNA SEWELL (D.O.B. 12/21/44) guilty of involuntary manslaughter for the incident, which took place inside Scott’s Talbot Street home on the evening of May 8, 2009. Sewell had been indicted for second-degree murder.

The verdict came after four days of testimony in which Assistant District Attorney Ian Polumbaum, a former domestic violence prosecutor now assigned to the DA’s Homicide Unit, proved that Scott was dead when Boston Police and emergency medical technicians responded to his home at about 7:30 that evening. Scott had called 911 to report that he had been stabbed “in the heart” by a woman who then left his apartment. He said he had removed the knife from his chest.

Scott’s cell phone and a bloody steak knife were found next to the chair.

Several hours later, the evidence showed, a Boston Police homicide detective took a break from processing the crime scene and saw Sewell seated at a nearby bus stop. The detective recognized her as fitting the description of a woman who had been staying with Scott.

In a subsequent conversation, Sewell made statements that she had been inside the building with a man who had struck her with a brick and that they had struggled over a knife. She agreed to go to Boston Police headquarters and gave a post-Miranda statement indicating that she and Scott had been drinking and that he attacked her with a knife rather than a brick. She stated that she never had control of the knife and that Scott was somehow stabbed in the struggle.

Sewell was examined by EMTs and at a nearby hospital. She had blood on her clothes but her only injury was an abrasion on her head that was not bleeding. She told hospital staff that Scott had fallen on the knife.

None of Sewell’s statements were borne out by an autopsy of the victim, which indicated that he died from a stab wound to his chest that was inflicted at a downward angle. He had also suffered a wound to his nose consistent with an injury from a sharp blade. Moreover, there was no sign of a struggle when first responders arrived in the apartment.

Sewell had posted bail and was free during trial on an electronic monitoring bracelet. At Polumbaum’s request, Judge Frank Gaziano revoked Sewell’s bail and scheduled sentencing for Nov. 4.

Katherine Moran was the DA’s assigned victim-witness advocate. Sewell was represented by attorney Aviva Jeruchim.
