Desha County Sheriff Don Smith said the search for Casey Crowder will be scaled back after more than 100 searchers failed to find a single clue as to the whereabouts of the missing Pine Bluff teen.

“Nothing has developed,” Smith said late Thursday afternoon. “We’re where we stood yesterday.”

Police have been searching since early Monday morning for the Watson Chapel High School student who failed to return home Sunday morning after visiting her boyfriend at his Pickens home.

Her abandoned vehicle was discovered on U.S. 65 in south Dumas sometime after she called her mother to tell her that her vehicle had run out of gas. When the vehicle was discovered, it had no gas in the tank, the doors were locked and the emergency flashers had been turned on.

Searchers combed farmland north and east of Dumas Thursday before going back over areas they searched earlier this week, including the 3,000-plus acre farm at Pickens where Crowder’s boyfriend lives, according to Smith.

“I think we’ve almost covered the Pickens Plantation,” Smith said. “We’re running down every tip we get but so far we haven’t found anybody who has seen or heard anything.”

Crowder is described as a blond-haired, green-eyed, 17-year-old white female, about 5-feet, 1-inch in height and weighing about 105 pounds. Anyone with information about her disappearance is asked to contact the Desha County Sheriff’s Office at (870) 877-2327.
