Real Names: Diana Lynne Shawcroft and Jennifer Sue Lueth
Nicknames: DiDi (Diana); Jenny (Jennifer)
Location: Phoenix, Arizona
Date: May 24, 1996
Details: In 1996, twenty-year-old Diana Shawcroft and her best friend, nineteen-year-old Jennifer Lueth, left their homes in Colorado and moved in with Diana's older sister Kristina in Glendale, Arizona. The three shared a small apartment and often got on each other's nerves. On May 24, after an argument with Kristina, the two friends left to go to a mini-mart a few blocks from their home. They didn't take anything with them, so Kristina assumed that they would be back soon.
At around 7PM, they arrived at the mini-mart. The cashier said that they bought cigarettes and soda. Instead of leaving the store, they lingered around outside for two hours. Then, an unidentified man in a blue truck drove up and began talking with the girls. After talking for a few minutes, they got into the truck and mysteriously vanished. Their families believe that the girls knew the driver.
Three months later, two hikers in a remote desert 100 miles north of Phoenix came upon the girls' bodies. The girls had both been murdered, but the cause of death could not be revealed due to the ongoing investigation. The area is extremely isolated, about sixteen miles from the nearest highway. Police began looking into the girls' personal lives to see if they may have crossed paths with their killer. While in Phoenix, they attended numerous parties and nightclubs. It is possible that they met their killer at one of these locations. However, no solid suspects have been identified.
Soon after the girls' bodies were found, their parents placed two crosses and pictures of the girls in that spot. After that, police put the area under occasional surveillance. Four years later, on September 29, 2000, police found that the pictures had been removed from their frames. Police believe the killer might have stolen the pictures because the location where the bodies were found was not told to the public. Despite this, the killer has never been identified.
Suspects: Police believe that the killer was very familiar with the area that the bodies were found in. The area, which was extremely isolated, was only accessible with the help of a pickup truck or four wheel drive. They suspect that the killer had personal knowledge of the area and may have hunted or camped there. Jennifer's father believes that the killer might have not acted alone, and that an accomplice was involved.
Police would also want to question the unidentified man in the blue truck. It is believed that the girls knew the man in the truck. According to the cashier, it appeared the man was friends with them. He has never been identified. At the time, the man was thirty-one to thirty-three years old, with dirty blond or brown hair and a week's growth of facial hair. He had scratches on his right arm and was wearing a greasy denim jacket. The pickup was described as an early 1980s Chevy with tinted windows, chrome bumpers, a broken taillight, several body dents and badly faded paint.
Extra Notes: This segment originally aired on the August 29, 2002 episode of Unsolved Mysteries. It was also profiled on Haunting Evidence.
Results: Unsolved. In 2010, new analysis was done on a strand of hair and fibers collected from the crime scene. Investigators are hoping that the evidence will help identify the killer. Sadly, Jennifer's father Robert passed away in 2014. Diana's mother Kathy passed away in 1997.
