Remains of missing Illinois woman Cheyann Klus found 5 years after she was last seen

The remains of an Illinois woman who vanished in Chicago more than five years ago have been found, her family says.

Cheyann Klus, of Downers Grove, was 22 in December 2017 when she was “reported missing by her father after she had not returned home after a few days,” according to the Cook County Sheriff’s Office.

Police say prior to the discovery of her remains, her last known contact was with a friend in Chicago that year.

“We have been looking for Cheyann, and information related to her disappearance, since she went missing over 5 years ago. While it was not the news we were hoping for, we have received confirmation from law enforcement that Cheyann’s remains were found,” her sister, Mariah Klus, wrote on Facebook.

“As her immediate family [father, sisters, brothers, nephews] in mourning, we ask for privacy as we grieve the unbearable loss of a daughter, sister, aunt, and a human being,” Mariah Klus added. “We plan to hold a private memorial service for Cheyann amongst us, but we hope that everyone can find solace in knowing that she has been found and respectfully laid to rest.”
