In interviews with law enforcement personnel, Lucas confessed to numerous additional unsolved killings. It was thought that there was positive corroboration with Lucas' confessions in 28 unsolved murders, so the Lucas Task Force was established by James B. Adams, the director of the Texas Department of Public Safety (DPS). The Lucas Task Force officially cleared 213 previously unsolved murders as a result of Lucas' confessions. Lucas received preferential treatment that was extremely lax for someone supposedly thought to be a cunning mass murderer. He was frequently taken to restaurants and cafés, rarely handcuffed, allowed to wander police stations and jails, and he even knew codes for security doors. Later attempts at determining Lucas' involvement in his confessed crimes were complicated when it was discovered he had been given access to information in the files of cases he was confessing to. There were suggestions that the interview tapes showed that Lucas would read the reactions of those interviewing him and alter what he was saying, thereby making his confessions more consistent with facts known to law enforcement. The most serious allegation against the Lucas Task Force is that they had let Lucas read case files on unsolved crimes, enabling him to come up with convincingly detailed confessions and making it virtually impossible to determine if he had been telling the truth about a relatively large number of the murders. In 1983, Lucas claimed to have killed an unidentified young woman, later identified as Michelle Busha, along Interstate 90 in Minnesota. When questioned by police, he gave inconsistent details on the way he murdered the victim and was eliminated as a suspect. In 1984, he confessed to the murder of an unidentified girl, referred to at the time as "Caledonia Jane Doe", who was discovered shot to death in a field at Caledonia, New York, on November 10, 1979. Investigators, however, found insufficient evidence to support Lucas' confession. In early 2015, over 35 years later, "Caledonia Jane Doe" was identified through a DNA match as Tammy Alexander. Lucas is also believed to have falsely confessed to the 1980 slaying of Carol Cole in Louisiana. Cole was also unidentified until 2015. Discredited Journalist Hugh Aynesworth and others investigated the veracity of Lucas' claims for articles that appeared in The Dallas Times Herald. They calculated that Lucas would have had to use his 13-year-old Ford station wagon to cover in one month to have
