Erie County District Attorney John J. Flynn announces that 41-year-old Jason M. Keenan of Town of Amherst was sentenced yesterday afternoon before Erie County Court Judge Kenneth Case to a determinate sentence of 6 years in prison followed by 4 years of post-release supervision.

On December 19, 2021, the defendant attempted to cause serious physical injuries to a co-worker by pouring a liquid cleaning agent into the victim’s drink. The victim unknowingly consumed the contaminated beverage and became ill. The incident occurred while the defendant and the victim were working inside of a restaurant on Niagara Falls Boulevard in the Town of Amherst.

The victim went WNY Immediate Care before he was transported to Millard Fillmore Suburban Hospital for emergency treatment. The victim was later transferred to Buffalo General Hospital where he remained in the intensive care unit for several days for caustic injury to his throat. The victim has since recovered from the injury.

Keenan pleaded guilty to one count of Attempted Assault in the First Degree (Class “C” violent felony) on April 5, 2022. The defendant pleaded guilty to the highest sustainable charge.

DA Flynn commends the Amherst Police Department, paramedics, physicians and other medical personnel for their work in this investigation.

The case was prosecuted by Assistant District Attorney David M. Zak of the Felony Trials Bureau.
