Super Bowl Sunday

At 10:45 on the morning of Sunday, February 3, 2019 — Super Bowl Sunday — nine-year-old Serenity Dennard ran out of the gymnasium at the Black Hills Children’s Home and into the trees. Staff chased her. They lost her.

Two witnesses saw her after that: walking north along rural Old Rockerville Road, a small figure in the cold. She was last seen by a woman dropping off a relative at the children’s home — about fifty yards north of the entrance, the last confirmed sighting. A grandmother and granddaughter in the area drove the road looking for her, looped back, and never saw her again.

Inside the facility, the response was unraveling. Staff were on three different radio frequencies, talking past each other. And the call to 911 — the call that starts every search — didn’t go out for 101 minutes.

By the time the Pennington County Sheriff’s Office took over, the temperature across western South Dakota was dropping toward subzero. Serenity wasn’t wearing a coat. What began as a rescue became, within days, a recovery effort. One of the largest search operations in South Dakota history — dozens of agencies, hundreds of searchers, dogs, aircraft, GPS-mapped grids across thousands of acres — found nothing. Not a mitten. Not a footprint that held. Nothing.

Who Serenity was

Serenity June Dennard was born May 12, 2009, in Sturgis. Her early life was instability itself: more than a dozen foster placements before Chad Dennard and Darcie Gentry fostered and then adopted her. She’d been described as having serious behavioral-health challenges rooted in early-childhood trauma — a child whose earliest bonds broke and who never quite learned to trust the new ones.

She had a history of running. Her adoptive father said she’d become adept at planning runaway attempts — and that she seemed to enjoy watching people search for her, treating it as a game. That’s why she’d been placed at the Black Hills Children’s Home, a residential treatment facility in a remote, wooded stretch of Pennington County: for structure, for help, for safety.

Her adoptive mother Darcie kept her bedroom ready for years. “Her bedroom is all set up for her, waiting for her to come home,” Gentry said in an interview. “Sometimes I just go in there and I cry. I lay down, I hold her unicorn, and I cuddle up in the blankets. It just completely rips your heart out.”

The investigation

Sheriff Kevin Thom’s office led a search that drew agencies from across South Dakota — Brown, Butte, Douglas, Hughes and Meade counties, police departments from Rapid City to Sioux Falls, the Civil Air Patrol, Wyoming search and rescue. Detectives interviewed every employee and former employee who’d had contact with Serenity — about 100 people — plus both sets of adoptive parents and her birth parents. None are considered suspects. They checked whether she’d contacted anyone outside the home by phone or computer before running. She hadn’t. By early 2021, investigators had pursued 275 leads and conducted 538 interviews; by 2023 the sheriff’s office said it had investigated 329 leads, with help from law enforcement agencies across the country (South Dakota News Watch). Sightings were reported from as far away as Las Vegas; none panned out.

Cadaver dogs picked up scents in the search area. Investigators couldn’t say whether the odors came from Serenity.

Captain Marty Hartland, who ran much of the investigation, has said he considers stranger abduction highly unlikely: the window was minutes, the road was traveled almost exclusively by locals in winter, and it was a frigid late morning on Super Bowl Sunday. “I can’t even begin to calculate the odds that someone who would be willing to violently abduct a child happened by on a rural western South Dakota road within the few minutes they had to do that and successfully abducted her,” he said.

Her father Chad has his own theory, and it shifts: “As far as what I think happened, it changes every day. But I think she’s out there; I truly don’t think somebody picked her up. I think she liked to run and she wouldn’t run very far, but she liked to see people looking for her. I think she watched people look for her and I think she went too far and got lost.”

In 2020, state Sen. Lynne DiSanto launched a public advocacy campaign — a website, Facebook page, and GoFundMe for reward money — that eventually curdled into a public social-media feud (reported by the Rapid City Journal).

Seven years on, Sheriff Thom’s line still stands: “Our goal has always been to bring Serenity home and so far, we haven’t been able to do that.”

Theories: what might have happened

Succumbed to the cold. The official leaning and the cruelest math: nine years old, no coat, subzero temperatures arriving that evening, rugged terrain. What undercuts it: one of the most intensive ground searches in state history covered the area for years and never found a trace — no clothing, no remains.

Abducted. The theory the family fears and investigators discount. The sighting window was minutes on an empty rural road; no vehicle was seen; no ransom, no witness, no evidence. Hartland’s statistical argument against it is strong — but “unlikely” is not “impossible,” and the absence of remains keeps the question alive.

Still alive. The hope her family voices — that someone took her in, that she’s out there. No credible sighting in seven years, no contact, no digital trace. Investigators found nothing to support it and have never stopped looking.
