Tennessee investigators have received roughly 1,000 tips in connection with the disappearance of 5-year-old Summer Wells from her Rogersville home last month. Hawkins County Sheriff Ronnie Lawson said none of them produced any results.

Summer’s father, Don Wells, told a newspaper reporter he doesn’t expect to see his daughter alive.

“We’ve had several people sneaking around there, but we’ve had them sneaking around at night,” said Wells, speaking of his 11-acre property on Ben Hill Road. “We’ve never had somebody up there at 5:30 in the afternoon that we know of. They didn’t come up the driveway. They came up a dog trail from the woods. The [police K-9] dog that they used, that’s where the scent took them. Down through the woods, not the driveway. At Ben Hill Road is where the dog’s scent ended.”

Investigators are still looking for a red pickup truck, possible a late 1990s Toyota, that may have been in the area where Summer disappeared June 15, 2021. It had full-sized ladder racks and white buckets in the bed.

Summer stands 3′ tall and weighs around 40 pounds. She was last seen wearing gray pants, a pink shirt and may have been barefoot. She has close-cropped blonde hair and blue eyes.

Neighbors and other area residents and businesses are being asked to check their home security and trail cameras for any evidence that may help locate Summer.

Investigators say the circumstances surrounding her disappearance have yet to be determined – but they said they were looking into “all possibilities.”

Her parents, Don Wells and Candus Bly, previously said they believe that she was lured out of their rural home and taken.

Both have criminal records in other states, and they’ve reportedly taken and passed lie detector tests in connection with Summer’s disappearance.

Authorities have not publicly announced any person of interest or suspect in the case. Tennessee Bureau of Investigation assistant special agent in charge Shelly Smitherman said that’s been “frustrating” for law enforcement in a video shared to Twitter Tuesday.
