A Boston man has been convicted of killing four people _ including a 2-year-old boy _ during a drug-related robbery in 2010.

    Dwayne Moore was convicted Monday during his second trial. Moore's first trial ended with a hung jury, and a second suspect was acquitted.

    The 35-year-old Moore was found guilty of four counts of first-degree murder for the fatal shootings. He was also convicted of home invasion and armed robbery, but was acquitted of three other charges.

    A fifth victim survived the shooting, but was paralyzed and is now in a wheelchair.

    Moore's defense lawyer attacked the star witness in the case, Kimani Washington, describing him as a ``snake oil salesman'' who himself committed the crimes. Washington admitted participating in the robbery, but said he left before the shootings in the Mattapan section of Boston.  (Associated Press)
