  • Staff Report 

Cayuga County Sheriff Brian Schenck announced the arrest of an inmate for assaulting a custody officer at the Cayuga County Jail.

The incident occurred as the officer was conducting routine rounds on October 24 when the inmate, identified as Sincere Harrison, attacked the officer with multiple closed-fist strikes to the head.


Following the altercation, during which the officer regained control with assistance, it was discovered that a handcuff key was missing. A search of Harrison’s belongings uncovered the key, leading to additional charges. Harrison now faces a second-degree assault charge, a class “D” felony, and a first-degree charge for promoting prison contraband, also a class “D” felony.

The charges come on top of previous accusations from an August incident involving the Auburn Police Department, where Harrison allegedly attempted to seize an officer’s weapon. He is scheduled for arraignment on these new charges on October 30th, 2023, as he remains detained for the current and prior offenses.
