Three days before Christmas in 1990, authorities entered an isolated vacation cabin in the mountains of Oakley, Utah. A rookie deputy found a crime scene that he could only describe as "looking like a mini war zone."
Linae watched in horror as the two men fatally shot her mother, Kaye Tiede, left, and her grandmother, Beth Potts, right, in cold blood. Linae and Tricia both witnessed their father, Rolf, center, being shot. The sisters were then kidnapped and taken from the cabin.
Before the men left the cabin, they poured gasoline and intentionally set the upper floors on fire in order to destroy evidence of their crimes. They forced the sisters to snowmobile down the mountain with one killer on the back of each vehicle.
Randy Zorn, Linae and Tricia's uncle, was by the gate at the main road. He had just arrived for a holiday visit when the sisters passed him on snowmobiles. He waved, but the girls ignored him in the hopes that the killers would not shoot him.
At a nearby parking lot, the killers forced the girls off the snowmobiles and into the family car. The car raced past their uncle as he ran up to talk to his nieces. Within minutes, Randy Zorn saw another snowmobile approach the main road.
Although the temperature was well below zero, the person on the snowmobile was not wearing a coat, gloves or helmet. His face was was swollen and bloody. When the rider got closer, Randy was terror stricken to realize that the person on the snowmobile was his brother, Rolf Tiede.
Neither Rolf's daughters nor the killers knew that Rolf had played dead after he had been shot. In her "48 Hours" interview, Tricia Tiede said that she later learned that her dad had been doused with gasoline and he caught on fire himself. He had to run into the shower and tear off his snowsuit while on fire. This is the shower where Rolf doused the flames.
Randy Zorn learned from his brother, Rolf Tiede, that intruders who broke into the cabin killed Rolf's wife and kidnapped his daughters. Randy then called authorities to get help for the girls and to get his brother airlifted to a hospital.
Armed with the information that Randy provided, the police mobilized to capture the suspects and save the young girls. The killers were apprehended after eluding roadblocks and engaging authorities in high-speed chase through several towns.
Deli and Taylor had hitchhiked their way up to the particular locale because Taylor had family that owned a cabin in the area. They spent several days on the mountain, breaking into a number empty of cabins. Authorities theorized that the men saw the family leave their home and had waited for them to return.
In the garage there was a 12 to 18-inch puddle of fresh blood. The blood was frozen solid by the sub-zero temperature. The first deputy on the scene described the smell of burning hair and clothing as he began to walk through the cabin.
Investigators found an extremely cold and bloody crime scene. The living room carpet was so drenched with blood that it pooled on the wood planks underneath; the oozing blood formed crimson colored icicles where it leaked through the cabin floorboards.

Authorities told "48 Hours" that the No. 1 concern in this particular case was rescuing anybody in the cabin who might need assistance. The second priority was to preserve the evidence at the crime scene. One of the most significant pieces of evidence was a video camera. Inside the video camera -- was a videotape.
The lead investigator on the case told "48 Hours" that when he watched the videotape, he had expected to see pictures of family talking, playing games and doing what families do. Instead there was audio and video of the suspects opening the Tiede family's Christmas gifts.
Beth Potts was laid to rest three days after Christmas. Linea Tiede's memory of her grandmother is that she had lots of energy and that she was a fun, vivacious, energetic and happy grandma. She was full of life.
Kaye Tiede was laid to rest the same day as her mother. Kaye was known as an extremely devoted mother, who would give up anything for her children. Daughter Tricia remembers her mother as being the perfect friend. She never passed a judgment on anyone. She was always loving and willing to open up her home to anyone.
Approximately five months after these crimes, Von Taylor pleaded guilty to two counts of capital murder. The state dropped all of the other charges against him in exchange for that plea. Taylor went for sentencing before a jury and the jury decided that Taylor should receive a death sentence for each murder.
Edward Steven Deli went to trial. Investigators expected that he would also be convicted of first-degree murder. Instead, he was convicted of second-degree murder, due to one hold-out juror. The death penalty was no longer an option. Deli was sentenced to five years to life in prison.
Tricia, shown, and Linae Tiede both testified at trial. Despite their youth, authorities felt that the two sisters they were excellent witnesses. They were very sure about the things they had seen and they were able to speak about the horrors of the day in a detailed and unemotional way.
The girls testimony was not without personal cost. Linae resented that as a victim, she had to put one of the murder weapons in her hands. She had watched her family murdered with these weapons and questioned why she had to touch them.
Linae married a childhood sweetheart after her previous marriage ended in divorce. She says that her husband, Nathan, changed her; that he opened his heart and gave her the freedom to do the same. Linae and Nathan now have a blended family with nine children between them.
Tricia is a divorced mother of two little girls. She says that when she looks into their eyes, she sees both her mother and her father. She loves her life now. Tricia says that the incident in 1990 doesn't define her, but has helped to make her who she is today.
After the fire, Rolf rebuilt the cabin and, according to the sisters, made it better than it was before. They still go the cabin and enjoy it with family and friends. Tricia told "48 Hours" that Von Lester Taylor and Edward Deli took their mom and their "Grams," but that they didn't take away the things that they still loved and enjoyed in their lives. For Linae and Tricia the cabin is magical and it's healing.
