NAME: James Cromitie
Background: Convicted in 1987 of misdemeanor drug possession; 12 later arrests for drug offenses that led to three felony convictions in 1989, 1990 and 1992, according to parole department spokeswoman Heather Groll.
He served prison time under three names: his own, the variation James Crometie and the alias "David Anderson." His most recent arrest was for selling drugs to an undercover officer near a New York City school.
Daphne Moore, a spokeswoman for Wal-Mart, confirmed that Cromitie worked at the Wal-Mart in Newburgh until three months ago.
NAME: David Williams
Background: Williams' aunt, Aahkiyaah Cummings, said he was a good father to his 7-year-old daughter and newborn son. He was introduced to Islam in prison but never talked about his faith, she said. He grew up in Brooklyn's Williamsburg section.
He was released from prison in April 2005 after doing just less than a year on minor drug and weapons charges. He violated parole in August 2005 and went back to prison until December that year, when he was released on parole in Brooklyn.
NAME: Onta Williams
Background: Williams served about three months in state prison on drug charges in Orange County. He was released to federal custody in August 2003, convicted of federal drug charges and sentenced to 70 months in federal prison. It is unclear when he was released.
His uncle, Richard Williams, said Onta is separated from his wife and she has custody of his three children, ages 6 to 15. He lived with his uncle until February, then moved in with his girlfriend.
NAME: Laguerre Payen
Background: State records show he was released on parole in August 2005 after serving just more than a year in prison for hitting two people with pellets fired from a BB gun and snatching purses from two women in Rockland County.
Hamin Rashada, an assistant imam at a Newburgh mosque, described Payen as penniless, jobless, quiet, evasive and paranoid. He had been fighting deportation to Haiti and for the custody of his 3-year-old son, who is living locally with the child's mother. Rashada said he was introduced to Islam in prison; the imam said he worried about Payen's lack of knowledge about the religion.
