Four months after an 87-year-old Irondequoit woman was killed in a hit-and-run, a Monroe County grand jury indicted a man in connection to the crime.

Vincent Mannillo, 62, of Greece has been charged with criminally negligent homicide, a felony, said Calli Marianetti, community relations coordinator for the Monroe County District Attorney's Office.

The indictment was unsealed when he appeared in front of Monroe County Court Judge Christopher Ciaccio on Thursday and pleaded not guilty, Marianetti said.

Joan Dierna was struck and killed by a vehicle on Nov. 10, 2018, while retrieving her mail from a roadside mailbox in the 300 block of Bayview Road, Irondequoit police said. The indictment alleges Mannillo caused Dierna's death.

Mannillo is due back in court on March 28, and will appear before Monroe County Supreme Court Justice Vicki Argento.
