Erie County District Attorney John J. Flynn announces that 43-year-old Mark Trykowski of Kenmore was sentenced on Friday morning before State Supreme Court Justice M. William Boller to 18 years in prison followed by 20 years of post-release supervision.

On Sunday, July 3, 2022, at approximately 6:40 p.m., the defendant forcibly engaged in sexual conduct with an adult female victim at a location in the City of Buffalo. The defendant was not known to the victim. After the attack, the victim was transported to ECMC where she underwent a rape kit. The defendant, who was a registered sex offender at the time of the crime, was linked to the crime through DNA and other evidence.

Trykowski pleaded guilty to one count of Criminal Sexual Act in the First Degree (Class “B” violent felony) on January 23, 2023.

As part of the sentence, Judge Boller issued a final order of protection on behalf of the victim, which remains in effect until March 2069.

District Attorney Flynn commends Detective Jennifer Vaccaro of the Buffalo Police Department, Erie County Central Police Services laboratory and the Sexual Assault Nurse Examiners at ECMC for their work in this investigation.

The case was prosecuted by Assistant District Attorney Andres D. Ortiz of the Special Victims/Domestic Violence Bureau.
