SALEM – Jurors are expected Wednesday to begin deliberating the fate of Blake Colella, the Swampscott native charged for a 2006 Lynn stabbing case outside the 7-Eleven convenience store on Essex Street.Colella, 25, who had been living in Lynn at an Essex Street apartment at the time of the incident, is on trial on charges of armed assault with intent to murder, assault with a dangerous weapon, assault and battery causing serious bodily injury and assault and battery with a dangerous weapon in connection with the May 19, 2006 stabbing of Richard Dalton, 21, and attack on his 17-year-old brother Joseph Dalton.The jury is expected to get the case at about noon after lawyers make their closing arguments in the case.During the final day of testimony Tuesday, Richard Dalton testified he was at the 7-Eleven store at 264 Essex St. that night and got into a pushing match with an individual who he did not know or could not identify. He pushed the man, believed by the commonwealth to be Colella, after the man touched his cousin?s arm and apparently made advances towards her.Dalton interjected with pushing and yelling before feeling a blow to his chest and left shoulder. After Colella and his younger cousin fled the store parking lot, Dalton noticed blood on his t-shirt.Dalton?s younger brother, Joseph, also testified, but never identified Colella as the attacker of his brother and assailant on himself.He testified he never saw a knife on the man wearing camouflaged clothing.The knife used during the incident has never been found.Dalton?s cousin, Starann Butler, 19, of Lynn, admitted taking her cousin Richard to Salem Hospital that night for a stab wound.But when Assistant District Attorney Michael P. Hickey asked Butler if she had picked out her cousin?s attacker through a photo array shown to her by police, she acknowledged she had, but said the photo shown to her in court was not the photo she picked, although she had initialed it.The photo was a picture of Colella. She also could not recollect even talking to police about the incident.One crucial piece of evidence introduced by the commonwealth concern taped conversations Colella had with his father, Angelo, from the Middleton Jail, which discuss the stabbing and the witnesses involved in the case.His attorney, Ronald J. Ranta, declined to elaborate if Colella will take the stand Wednesday morning in his own defense before closing summations by the commonwealth and defense.
