WILLISTON — The search for a Williston man continues in the area around his home in Judson Township in Williams County.

Roger Shelton, 61, was last seen on Jan. 5 near his home in the residential area of the township located west of Williston. Shelton was first reported missing to law enforcement by his son on Sunday evening.

Williams County Sheriff’s Deputy Daniel Ward said Shelton’s vehicles and personal effects such as his cell phone, wallet and medication remained at his home.

The search was delayed due to flurries and the setting sun but the Williston Police asked residents of the township to search their out-buildings, barns and other structures for Shelton as a more comprehensive search was mounted.

An organized search of the township involving Williston Police Department, North Dakota Highway Patrol, county and city emergency management and a number of private citizens was coordinated on Tuesday.

Ward said about 16 private citizens took part in Tuesday’s search, with everyone given assignments to ensure full coverage of the approximately five square miles within the township.

However, a release from Tuesday evening indicates Shelton has still not yet been located.

Ward indicated that authorities were turning their attention toward investigating leads and tips they’ve received from Shelton’s friends, family and some anonymous sources.

“We’re trying to track down the last place that we do know he was at. Whether it be at the doctor or Walmart or a gas station. We’re trying to track down any camera footage to track down the last known place that we can find out he was.” Ward said, “We encourage people who think they see something to call us.”

No further updates were provided on the search. Ward directed anyone with information to reach out to the department’s tip line.
