Suspect Awaits Extradition For 1992 Cold Case Murder of Helen Cardwell In Niles

NILES, Ill. (CBS) -- Nearly 29 years after a woman was murdered in Niles, police are charging a man with her death.

Thirty-five-year-old Helen Cardwell was found strangled in her room at the since-shuttered Leaning Tower YMCA, 6300 W. Touhy Ave., on Nov. 8, of 1992.

In 2020, Niles police formed a cold case team and were able to get DNA from evidence in the case. The crime lab got a match, but detectives couldn't find the suspect, Richard Sisto.

He was taken into custody in Texas in 2021, where Niles detectives interviewed him and collected a DNA sample.

Detectives and Cardwell's family were relieved to have answers in her death.

"It was something that has been in their heads and it was frustrating at the time," said Detective Mike Boba of the Niles Police Department. "And I know they appreciate we were able to reopen the case and bring some closure."

"I'm so grateful they decided to reopen this case. And I just appreciate everyone's efforts in solving her murder," said Noca Ervin, the victim's sister.

Sisto is now awaiting extradition to Illinois.
