Sheriff: Convicted sex offender in Illinois sent threatening emails to woman and her employer

DUPAGE COUNTY, Illinois. – A convicted sex offender was arrested by DuPage County police last week for allegedly sending threatening and intimidating emails to a woman and her employer.

Christian J. Warzyva, 54, is accused of identity theft, failure to register as a sex offender, intimidation, threats and possession of a false identity card.

Vincent J. Cassano was first reported missing and in danger in February 2023. Investigators with the DuPage County Sheriff’s Office found him at the Salvation Army Center in Rockford, Illinois.

After he was located, a criminal investigation was launched into unauthorized credit card activity and intimidating and threatening emails sent to the victim and her employer.

It was determined that Vincent J. Cassano’s real identity was Warzyva, who had been charged and convicted of aggravated sexual abuse of a three-year-old victim in Sangamon County, Illinois nearly 20 years ago. It was also determined that Warzyva was an uncooperative sex offender.

After 18 months, Warzyva was arrested on July 3 by the sheriff’s office and U.S. Secret Service agents.

Warzyva also had arrest warrants for violating the Sex Offender Registration Act and an order of protection under his alias.

He is being held in the DuPage County Sheriff’s Office Jail pending trial and remains under investigation by the U.S. Secret Service.
