Olsingch Blanc, 31, was last heard from on June 1, 2023, while living in Tulsa, Oklahoma. Concern grew in early summer 2023 after his sister reported she had not heard from him since sometime in June. Blanc is between 5 feet 7 inches and 5 feet 9 inches tall, with black hair and brown eyes. He was known to have lived on tribal land.

The Tulsa Police Department opened an investigation under case number 2023-061081 and the case was entered into the National Missing and Unidentified Persons System as MP124117. Authorities and missing person organizations have been involved, but few leads have emerged and there were no initial signs of foul play reported. The investigation remains active.

If anyone knew Olsingch, saw him around late May or early June 2023, or has information about where he may have gone, please contact the Tulsa Police Department with any details.
