LAKE COUNTY, IL — Authorities say the investigation into the disappearance of Ruslan Furman remains active, with detectives identifying likely suspects but still searching for the missing man.
Detectives with the Lake County Sheriff's Office have collected evidence at two homes in unincorporated Mundelein — including the residence where Furman had been living — that confirms foul play may be involved, Lake County Sheriff's Office Chief Christopher Covelli told Patch.
Covelli said investigators cannot disclose the specific evidence gathered because the criminal investigation is ongoing.
Authorities believe Furman was last seen around Nov. 5, 2025, and investigators think his disappearance occurred around that time.
Detectives have carried out numerous searches in the surrounding area, including searches in Diamond Lake, but Furman has not yet been located, Covelli said Monday.
While Covelli said investigators have identified “likely suspects” in Furman’s disappearance, but he emphasized that the case remains very active and detectives continue to pursue leads.
Meanwhile, a Mundelein man who was previously arrested during the investigation into the disappearance of Ruslan Furman, 51, was taken into custody again earlier this month.
Authorities said Dmitry Bogatiryov, 52, was initially arrested in November along with another man after investigators executed search warrants connected to the missing person investigation, according to media reports.
During those searches, deputies reportedly found firearms and large amounts of cannabis, leading to drug and weapons charges against Bogatiryov and Damen Voranoff, 56, of Mundelein. Bogatiryov was recently arrested again after investigators conducting another search allegedly discovered more cannabis and ammunition at his residence, violating his pretrial release conditions, according to the Lake & McHenry County Scanner.
Prosecutors have said the case was possibly a homicide several times in court, according to the media report. A petition to deny pre-trial release for Bogatiryov was granted following his second arrest.
Furman was last known to live in the 16500 block of North Route 83 in unincorporated Mundelein and had not been seen for more than a week when deputies began investigating his disappearance.
Officials are asking anyone with information about Furman’s disappearance to contact sheriff’s detectives at 847-377-4000. Covelli also encouraged community members to come forward if they know anything that could help advance the investigation.
