in. All personal property was left behind including purses, money, cars, keys, cigarettes, and the family dog. Later developments On December 31, 1992, a man called the America's Most Wanted hotline with information about the women's disappearances, but the call was disconnected when the switchboard operator attempted to link up with Springfield investigators. Police said the caller had "prime knowledge of the abductions" and publicly appealed for the man to contact them, but he never did. Levitt and Streeter were declared legally dead in 1997. However, their case files are still officially filed under "missing". Investigators received a tip that the women's bodies were buried in the foundations of the south parking garage at Cox Hospital. In 2007, crime reporter Kathee Baird invited Rick Norland, a mechanical engineer, to scan a corner of the parking garage with ground-penetrating radar (GPR). Norland found three anomalies "roughly the same size" that he said were consistent with a "grave site location"; two of the anomalies were parallel, and the other was perpendicular. Springfield Police Department (SPD) spokesperson Lisa Cox said that the person who reported the tip "provided no evidence or logical reasoning behind this theory at that time or since then." She also said the parking garage began construction in September 1993, over a year after the disappearances. "Digging up the area and subsequently reconstructing this structure would be extremely costly, and without any reasonable belief that the bodies could be located here, it is illogical to do so, and for those reasons SPD does not intend to. Investigators have determined this lead to not be credible." Darrell Moore, a former assistant at the Greene County Prosecutor's Office, said the tip came from someone who either "claimed to be a psychic or claimed to have a dream or vision about the case". Suspect In 1997, Robert Craig Cox, imprisoned in Texas as a convicted kidnapper and robber, and the suspect in a Florida murder, told journalists that he knew the three women had been murdered and buried and claimed their bodies would never be recovered. In 1992, Cox had been living in Springfield and, when interviewed then, had told investigators that he was with his girlfriend at church the morning after the women disappeared, which she corroborated. However, she later recanted her statement and said that Cox had asked her to say that. Cox also stated that he was at the home
