Tharp was serving time for drug and weapon charges. He was scheduled to be released in December 2019, according to police.
"Don't approach him, that's what we're asking," said Joe Nichols, Crime Prevention Officer with Oshkosh Police. "Safety and vigilance is always a good thing no matter what your day is, whether it's an escapee or just a regular day. But if you happen to see him, call the police."
No one was injured during Tharp's escape. Officers are continuing to conduct a search of the surrounding area with the Omro Police Department's K9 unit.
