In court, Judge Alan Honorof told defendant Ronnie Duren "all I can do by this sentence is to protect the community." He said there is nothing he can do to help the family of the man Duren killed, Michael Prophet, 35, of Valley Stream.
Duren's lawyer, Brian Carmody of Westbury, said he will appeal the conviction.
Prosecutors said in April 2011 Duren got into Prophet's blue Ford at the McDonald's restaurant on Peninsula Boulevard to carry out a drug deal. Duren then pulled out a handgun and shot Prophet in the back, prosecutors said.
Duren then fired three more shots, hitting a passenger in Prophet's van, Hayden Forrest, 35, of Uniondale, in the right shoulder, as well as Prophet's friend, Henry Fowler, 28, of West Hempstead, in the left arm. Both Forrest and Fowler survived the shooting.
Duren was arrested a month later. He was convicted in October of second-degree murder, second-degree attempted murder and other charges.
Prophet's sister-in-law spoke angrily as she asked Honorof to sentence Duren to the maximum. "I'm positive you don't care about Michael's lost life," Barbara Prophet said, addressing Duren. "My hate for you knows no bounds."
When Honorof announced Duren's sentence, Prophet's family let out a cheer with one woman shouting, "Thank you, Jesus."
This story has been changed to correct Michael Prophet's hometown and to correctly identify Barbara Prophet as Michael's sister-in-law.
