Identical twin brothers nearly pull off perfect crime
Heather DeWild was a 30-year-old mother of two when she went missing on July 24, 2003.
Heather and Dan DeWild
Heather's family immediately suspected her husband, Dan DeWild, was behind Heather's disappearance. They were two days away from finalizing their divorce.
Heather DeWild and her children
On the day she vanished, Heather had taken her children, Jacob and Hannah, to her soon-to-be ex-husband's home to sign a check and pick up health insurance cards.
The insurance cards
The insurance cards were never picked up and the check was never signed.
Dan DeWild and his children
Dan DeWild told Heather's worried family that she left the children with him to go shopping, but they instantly suspected that was a lie. The young kids couldn't say where their mother had gone.
Dave Springer
Heather's father, Dave Springer, was a veteran of the Denver Police Department. His instincts told him that something had happened to his daughter. He suspected Dan DeWild was involved but he had nothing to prove it.
Dan DeWild's house
Dan DeWild's home in Edgewater, Colo., is the last place Heather was seen alive. Police searched the house but found no evidence of foul play.
David and Dan DeWild
Dan's identical twin brother, David DeWild, left, had moved in, and was helping out financially so Dan, right, wouldn't lose his house.
David and Dan DeWild
Growing up, the twins were inseparable. David, on the left, and Dan on the right, both worked as mechanics for the transit authority. But people who knew them said there was a difference: Dan was more controlling than his brother.
David DeWild's Suburban
Police didn't have much to go on. No one had seen Heather since she had been at Dan's house, her car was missing and there was no sign of any foul play. They soon learned that Dan's twin, David, took his Suburban to be repaired 15 miles away -- an interesting move for a professional mechanic.
Sniffing for a scent
A week after Heather disappeared, a trained police dog identified decomposing scent in David DeWild's Suburban.
Heather DeWild's car found
Then, on Aug. 4, 2003, police found Heather's car, a white Nissan Sentra, in the parking lot of a nearby apartment complex.
Heather DeWild's car found
The passenger's side window was left open, and the car had been wiped clean -- there wasn't even evidence that Heather had been in it.
Road worker finds body
One month later, Curtis Johnson was moving dirt on a canyon road, when he uncovered Heather's body.
Crime scene evidence
Heather had been wrapped in trash bags with a duct tape mask on her face. Her body was so decomposed, there was no way to even determine how she died.
Heather DeWild laid to rest
Heather was laid to rest with the epitaph "All she wanted was to love and be loved in return."
Heather DeWild and her sisters
The Springer family -- including sisters Rebecca, center, and Jennifer, left -- continued to ask for Heather's killer to be brought to justice, but police didn't have enough evidence to charge anyone. "After a while, you just think ... Is anything ever gonna happen?" Rebecca said.
New D.A. on the case
When Scott Storey, right, was elected the Jefferson County, Colo., district attorney, the Springer family begged him to look into Heather's death. Storey promised he would and set up a task force.
David DeWild shows how Heather was killed
In a surprising turn of events, David DeWild, shown here, flipped on his twin brother. He showed investigators how he says Dan killed Heather in the garage. David explained they had taken efforts to leave no evidence behind -- an idea they got from watching crime shows like "CSI."
Dan DeWild on trial
At Dan's trial, a jury convicted him on two lesser counts, but they were deadlocked on the first-degree murder charge. They couldn't all agree that Dan was the twin who actually killed Heather.
Justice for Heather DeWild
Facing another trial and the possibility of life in prison, Dan took a plea deal for second-degree murder and was sentenced to 74 years. The jurors say that they couldn't have voted to convict Dan for Heather's murder without his twin brother's testimony.
