Juri R. Leis, an 80-year-old man from Frankfort, Illinois, has been missing since the spring of 2023. His last known contact was a voicemail left for a friend of his son on April 2, 2023. He was reported missing on June 6, 2023, after the Frankfort Police Department could not reach him and repeated welfare checks from family and an acquaintance who helped with groceries failed to turn up recent contact.

Investigators found no recent bank transactions and his phone was disconnected, prompting authorities to upgrade the case to endangered missing on July 13, 2023. He is described as 6 feet 3 inches, about 150 pounds, with graying hair and brown eyes. A single tip came on July 17, 2023, from a caller who said they saw a frail elderly white man matching his description walking eastbound on 175th Street near George Brennan Highway in Tinley Park on the evening of July 16, 2023; the witness returned with water but the man was gone.

There have been no further public leads and the case is currently cold. If anyone saw Juri Leis after April 2, 2023, or recognizes the man seen in Tinley Park, please share information with the Frankfort Police Department.
