Her behavior surfaced after her brief appearance in the 1983 cult film 'Scarface'. The film was popular during an era when drug trafficking was running rampant throughout the state of Florida. Within the same week of her disappearance, she mentioned to her mother, Linda Curtis, that someone was trying to kill her. She refused to eat because she feared the food contained poison, and she also battled insomnia.

At the time of Tammy Lynn's disappearance, Christopher Bernard Wilder was wanted in the area. He was known for posing as a magazine photographer in order to lure aspiring models. Police suspected him to be a serial killer with a count of 8-12 victims who were all women from Florida to California. However, he was never linked to Tammy Lynn and was killed during a shootout with police in 1984.

The friend who Tammy Lynn had been hanging out with mentioned he dropped her off not too far from the 'Glass Bank' (which has since been demolished), and he was clueless as to where she had gone after she walked away while barefoot. Although he wasn't considered a suspect, Tammy Lynn expressed that she feared him.

To this day, Tammy Lynn's whereabouts, whether alive or dead, remain unknown. Before Linda's death in 1995, her dying wish was for her daughter to be found.

Ron Jackson, a trucker, claimed he saw a man who fit John's description loitering in front of White's Truck Stop in Raphine, Virginia. His clothing was neat and his dress shirt was 'so clean and white'. He was wearing a pair of moccasins and appeared to be disoriented. While both men talked over breakfast at the truck stop, the man mentioned he was staying in a homeless shelter. Soon, they parted ways.

Prior to John's disappearance, he was working 18-hour days, as a financial officer, and was set to collect one million dollars. His father, Richard Cheek, mentioned that his son was overworking himself, and was possibly under so much stress that he detached himself from reality. He also confirmed that his son owned the same moccasins which Ron claimed he was wearing.

He suffered blunt-force trauma to his stomach. Also, his pants were turned inside-out and $4,000 (in U.S., German, and Canadian currency) as well as $2,000 worth of gold/platinum jewelry was scattered around him.

Prior to Blair's death, he had embarked on a strange journey from July 5th - July 11th. During several attempts to pass U.S. Customs, he was turned away because he had a large sum of money in his possession -- a common characteristic of a drug trafficker. Soon, he suddenly showed up at a friend's house in the middle of the night to ask her if she could drive him to the Canadian-American border, but she declined. He revealed to her that someone was trying to kill him, but then he bid her a farewell and left. Not too long after, his last attempt to pass U.S. Customs was successful.

At one point, Blair purchased a round-trip plane ticket for a flight from Vancouver to Frankfort, Germany. Although he showed up the next day, as scheduled, to turn in the ticket, he left and never returned. Also, he was captured on a hotel surveillance camera repeatedly entering and exiting while looking over his shoulders as if he were anticipating someone or something. However, after he finally paid for a hotel room, he left and never returned to claim it.

On the day of Blair's death, during an investigation, there were no signs of foul-play nor were there signs of an accident. Overall, there is no valid reason(s) for his journey, the circumstances surrounding his death, nor what he could've been running from. Or if he were running from himself.

He managed to dodge Joseph in the kitchen and then ran though a glass door to escape.

Frank reported the incident to a security guard on the premises which launched a search by two police officers. As the officers searched for Joseph, they found the bodies of his wife, Judith, and two step-daughters, 12-year-old Kristy and 20-year-old Wendy. They had been murdered and were dead for nearly 24 hours. Joseph was the prime suspect because he was the only male occupant in the house at the time.

When police conducted an investigation, they concluded Bill was beaten and strangled. After he was murdered, his wallet and pick-truck was stolen. Only a few days later, a man found Bill's wallet on an Interstate and left it at a local police station. Bill's truck was found one day later after it was abandoned outside of Chicago, Illinois.

On the day of Bill's murder, two young men reported a stolen pick-up truck which bared a similarity to Bill's. The men mentioned riding with an unidentified man who they feared. When they all arrived at a rest stop near Oklahoma City, they informed the attendant that they suspected the truck was stolen. Strangely, the truck hadn't been previously reported.

A composite sketch of a suspect circulated, but no arrests were made.

15 years later, Lawrence Tutt, a career criminal and drug addict, was connected to Bill's murder.

2. Beverly Ann McGowan

When 34-year-old Beverly Ann McGowan was found mutilated near a canal in St. Lucie County, Florida on July 18, 1990, who was responsible for her murder and why she was murdered was unknown.

Prior to Beverly Ann's death, she had advertised for a roommate. A woman who identified herself as "Alice" responded and they both scheduled to meet at Beverly Ann's condo. "Alice" mentioned she was skilled in numerology; so she performed a reading. Beverly Ann revealed confidential information about herself only to be contacted later with a request for additional information.

The identity of "Alice" was connected to a woman named Elaine Parent. According to a criminal record, Elaine lived a life of crime out of high school. For a woman of average height, as well as an appearance which was unassuming, she was known to have a ferocious temper. One of her ex-partners confirmed she was so fearful of Elaine that she once drove 80 miles past her own home because she knew Elaine was there.

As evidence mounted against Elaine, regarding her involvement in Beverly Ann's murder, she continued to elude capture in the United States as well as the United Kingdom.

By 2002, Elaine was residing in Florida and during that same year she received a visit from the police. She committed suicide, by a gunshot to the chest, as they waited for her to change her clothes in order to be escorted to the police station to be questioned.

1. Marie Lilienburg and Maria Wahlen

Sweden natives 23-year-old Marie Lilienburg and 25-year-old Maria Wahlen were found dead in a creek in Santa Maria, California in August of 1983.

Both women were working as maids at a local motel to earn money during their temporary stay in Los Angeles. Before preparing to return to Sweden, they decided to tour the coast and continued to hitch rides with strangers in order to get to specific locations. After their bodies were found, police interviewed the drivers who picked up both women. They received a tip about a man identified as "Loren" who was seen driving away with both women in a van. The man became a suspect who turned out to be Loren Herzog.

While under pressure during an interrogation regarding the murder of a hunter in 1994, Loren implicated Wesley Shermentine, who was a long-time friend. Both men were drug addicts and favored speed as their drug of choice. While under the influence, they embarked on a journey of murder which started in 1984. Since they were both seen around the same areas which Marie and Maria hitched rides, Wesley was considered a suspect alongside Loren. Although Loren confessed to the murders, he and Wesley were never connected to them.

Loren committed suicide in prison in 2004.

Wesley is serving a life sentence.
