A Suffolk Superior Court jury today convicted James Witkowski of first-degree murder for the rape and suffocation of Lena Bruce in her South End apartment on July 12, 1992, the Suffolk County District Attorney's office reports.
The conviction means a mandatory sentence of life without parole.
Witkowski, 45, had evaded arrest until 2014, when he violated the terms of an assault-and-battery conviction, and was required to supply a DNA sample, which matched evidence found at the murder scene.
Prosecutors say Witkowski did not know Bruce when he attacked her. Bruce, 21, a Philadelphia native, had graduated with honors with a degree in electrical engineering from Tufts University just two months before her death.
