Marchello Gildersleeve found guilty in the brutal 2022 killing of Daniella Patterson.

LOCKPORT, NY – In a significant legal development, Niagara County District Attorney Brian D. Seaman announced that a Niagara County jury has returned a guilty verdict in the murder case against Marchello M. Gildersleeve, 43, of Niagara Falls. Gildersleeve was convicted of Murder in the Second Degree and Criminal Possession of a Weapon in the Second Degree for the fatal shooting of 35-year-old Daniella Patterson in December 2022.

“This defendant opened fire from close range, killing a young woman while she sat defenseless in a car. He continued to fire at the victim as the car drove off. This killing was cold-blooded and deserves an extremely harsh sentence, which we will ask the judge to impose at sentencing,” Seaman stated.

The harrowing case was meticulously investigated by the Niagara Falls Police Department. The prosecution team, led by First Assistant District Attorney Doreen Hoffmann and Assistant District Attorney Mattie Davis, presented compelling evidence that resulted in the conviction.

Gildersleeve faces a possible sentence of 40 years to life in prison. He is scheduled to be sentenced by County Court Judge Caroline Wojtaszek on August 30th.
