Incarcerated music executive James “Jimmy Henchman” Rosemond reportedly had the last laugh after weeks of insults shot his way courtesy of rap foe 50 Cent in light of a high-profile trial coming to an end.

According to reports, a mistrial was determined in Rosemond’s G-Unit affiliate murder case.

A judge has declared a mistrial in the murder case of a hip-hop promoter already serving a life sentence for smuggling cocaine. U.S. District Judge Colleen McMahon made the ruling Friday in Manhattan federal court after the jury said it was deadlocked. Federal prosecutors had charged James Rosemond and Rodney Johnson in the 2009 shooting death of Lowell Fletcher, an associate of G-Unit. They say the killing was payback for an assault on Rosemond’s son. Rosemond’s lawyer had argued the witnesses against him were unreliable. (Billboard)

One of Henchman’s former workers had accused him of being blood-thirsty and focused on murder during the Unit feud.

“He said, ‘These dudes ain’t going to be happy until they go to a funeral,’ ” testified Khalil Abdullah, who said he was one of Mr. Rosemond’s managers in the drug ring. Mr. Abdullah also testified last year, when Mr. Rosemond was convicted in Federal District Court in Brooklyn of running a cocaine ring that pulled in $11 million a year. Prosecutors in Manhattan sought a separate trial on the murder charge for Mr. Rosemond and one of his alleged co-conspirators, Rodney Johnson. (New York Times)

Another witnesse, Mohammed Stewart, claimed to have worked for Henchman and said he staked out various G-Unit affiliate homes.

As the feud escalated, Mr. Stewart said he was asked by Mr. Rosemond to take part in several tit-for-tat acts of violence. In 2007, he slashed Mr. Lighty’s brother with a razor in the street. He also admitted he had shot up a house on Staten Island belonging to Baja Walters, a road manager for G-Unit. Mr. Stewart said he spent many nights with Mr. Rosemond staking out 50 Cent, Tony Yayo or Mr. Lighty, looking for a chance to shoot them. “He said that, you know, they’re not going to understand what it is until they are carrying a coffin and they’re crying, like ‘I miss my homie,’ ” Mr. Stewart said.
