A man convicted of two murders during an unusual double-jury trial was sentenced Wednesday to 75 years to life in state prison, the Monroe County District Attorney's Office said.

Syjesman T. Brown Jr., 33, was found guilty May 17 of second-degree murder in the 2017 slayings of David Jones and Alexander Powell. Brown was also convicted of attempted second-degree murder, second-degree assault, attempted first- and second-degree robbery, two counts of second-degree criminal possession of a weapon, and attempted fourth-degree grand larceny.

His co-defendant, Imani Williams, was acquitted by a jury on May 8 in the slaying of David Jones Jr. on May 27, 2017. State Supreme Court Justice Alex R. Renzi dismissed the second-degree murder charge facing Williams in the May 14, 2017, slaying of Powell. Renzi said there wasn't enough evidence in that case to proceed to a jury.

They were tried together but before two separate juries. Williams, however, was found guilty of attempted second-degree robbery and attempted fourth-degree grand larceny in an unrelated incident from July 26, 2017.

The Williams verdict wasn't released to the public because Renzi issued a gag order to ensure the jury considering the Brown case wouldn't be improperly influenced.

Double jury trials can be utilized when the evidence is linked to multiple defendants, but it might only apply to one of the accused and not the other.

Brown killed Powell, 24, whose body was found in a vacant lot with "dozens of stab wounds," prosecutors said. Brown received 25 years to life for the murder of Powell.

Brown fatally shot Jones, 34, in the head while in Genesee Valley Park shortly before 6:20 a.m. May 27, 2017. Jones' burned body was found by a bicyclist on a pedestrian bridge. Brown also received a sentence of 25 years to life in the murder of Jones.

On July 26, 2017, Brown and Williams were accused of shooting a man on Hoeltzer Street during a robbery attempt. The victim fled the scene and survived his injuries, prosecutors said. Brown was given 25 years in prison with five years of post-release supervision for the attempted murder, assault, and attempted armed robbery.

The three prison sentences will run consecutively.

Brown and Williams originally were to be tried separately before Renzi. However, in January a month-long trial of Brown ended with a mistrial after a juror took ill deep into the deliberations.

Afterward, Renzi opted to try the two defendants together with dual juries. The two also faced charges connected to a gunpoint street robbery in July 2017.

Special Assistant District Attorney Patrick Gallagher and Senior Assistant District Attorney Derek Harnsberger prosecuted the case.

Williams was sentenced last month to seven years in state prison.

Monroe County District Attorney Sandra Doorley said prosecutors were satisfied that Brown was "sentenced in a manner that reflects the severity of his actions."
