​​​ST. PAUL — An anonymous donor is offering a $10,000 reward for information leading to the arrest and conviction of the person or persons who murdered Cheryl Prokop in 1988 in her St. Paul home.

Someone entered Cheryl Prokop​’s residence at the Vista Village Townhomes on Kansas Street and strangled her overnight on Thursday, Dec. 2, 1988. Prokop’s 4-year-old daughter found her mother’s body later that morning and went to the apartment caretaker’s office to report the death.

The St. Paul Police Department and Minnesota Bureau of Criminal Apprehension (BCA) have been actively investigating the murder since it happened, but so far no information has led investigators to the killer. Now, an anonymous donor is offering the reward in the hopes it will encourage someone to come forward with information about t​he incident.

“We as a department never forget victims and their families who are left behind seeking answers,” said St.​ Paul Police Chief Axel Henry. “We will continue to seek those answers and are committed to providing closure for families and bringing every offender to justice.”

“Despite decades of forensic and investigative efforts, available evidence has not led us to the person or persons responsible for Cheryl’s death,” BCA Superintendent Drew Evans said. “But we’re continuing to work this case and are hopeful the reward will result in new information.”

If a tip is received that leads to an arrest and conviction in this case, the anonymous donor will dispense the reward in coordination with the family and law enforcement.

“We’ve waited for 35 years to understand why Cheryl was killed and who did it," her father, Dick Prokop, said. "Nothing can bring her back, but maybe this reward will help lead to some answers. If you know what happened, please report what you know.”

Anyone with information about who is responsible for Cheryl Prokop’s murder is urged to contact the BCA at 877-996-6222, via email at bca.tips@state.mn.us, or through the BCA’s See It Say It Send It tip app. Information can be provided anonymously.
