Federal prosecutors have had their last shot to convince a New Jersey jury that a well-known attorney was responsible for the killing of a federal informant nearly eight years ago.

Jurors heard more than four hours of closing arguments from the government Monday in the trial of Paul Bergrin, whose clients once included Queen Latifah and other entertainers.

Bergrin is accused of murder conspiracy and aiding and abetting the murder of Deshawn "Kemo" McCray in 2004. McCray was to testify against one of Bergrin's clients in a drug case.

Assistant U.S. Attorney Joseph Minish called McCray's death "an execution" and told jurors Bergrin stood to gain because he also was involved in the drug trade.

Bergrin is representing himself and will present his summation on Tuesday morning.
