Apparently he and Rachel saw each other and spoke briefly. The man claimed that another person appeared to be with the girls. During this same time, some women's clothes were found in the Justin, Texas, area and were investigated, but it was determined that they did not belong to the girls. By spring of 1975, the families grew frustrated with the Police investigation and decided to hire a private detective named Jon Swaim. In August 1975, Swaim discovered that a 28-year-old man was making a string of obscene phone calls in the area. This man had worked for a store in south Fort Worth where Rachel had applied for a job just before Christmas. It was discovered that he was using his position to obtain information from young women who had either applied for a job at his store or who were listed as references. Six women who had applied at this store had been receiving obscene phone calls. He also once lived in the neighborhood of Rachel's parents but moved away shortly before she married. In the end, nothing ever came of this suspect. In April 1975, Swaim went to Port Lavaca with 100 volunteers to search under bridges in the area after receiving a tip that the girls had been killed and taken there. However, no trace of the girls was found. A year later, it was reported that three skeletons were found in a field outside of Alvord, Texas, by an oil drilling crew. Mr. Swaim had the bones checked against x-rays and dental records of the girls, but it turned out that the bones belonged to a teenage boy about 15–17 years of age and two other females who were not identified as being any of the girls. In March 1976, a psychic called one of the families and told them that the girls could be found near an oil well. For some reason, the searchers focused on the small community of Rising Star outside of Abilene, but nothing was ever found. In 1979, Jon Swaim died following a drug overdose; his death was subsequently ruled to be suicide. Upon his death, he ordered that all of his files on the case be destroyed. In the spring of 1981, police investigators were called to a location in Brazoria County after human remains had been found in a swampy area. After a month of investigation, they discovered that the bones did not belong to the three girls. In January 2001, the case was reopened and assigned to a homicide detective, Tom Boetcher. He believes the girls left the mall with someone they trusted. He stated, "We can say that they were at one point seen with one individual, but we believe there was more than one involved".
