billboards in the Tampa Bay area, leading to a call from a former neighbor who provided a copy of a work order Chandler had written. This use of billboards by law enforcement in the US was unusual at the time. Through handwriting analysis, the two samples were matched. A palm print on the brochure was also matched to Chandler, who had sold his boat and left town with his family soon after the billboards appeared. Police reported that Chandler and his then-wife moved from their home on Dalton Avenue in Tampa to Port Orange near Daytona Beach. Second suspect theory Investigators originally thought two men were involved in the murders of the Rogers family. This theory was used for an enaction shown in a 1991episode of Unsolved Mysteries. This theory was dismissed when Chandler was arrested. No evidence of a second manother than a former prison cellmate's claim that Chandler said another man, whose identity the cellmate claimed to know but would not revealhas ever surfaced. The second-suspect theory was belied by Chandler's approach of two Canadian female touriststhat he was willing to approach multiple potential targets by himself. Hal Rogers's brother John was also considered a suspect, even though he was serving a prison sentence for the rape of a woman at the time of the murders. Police investigating the woman's rape allegation found evidence indicating John had also sexually assaulted Hal's daughter Michelle, although charges involving this assault were later dropped because of her reluctance to testify. The St. Petersburg Times said John may have planned the murder during a visit to his parents' property near Tampa a month before the murders. Once the police established John could not have hired a contract killer, did not have accomplices, and could not have known the timing of his sister-in-law's and nieces' trip, he was dismissed as a suspect. Hal was also considered a suspect because he had posted bail for his brother, he states in an episode of On the Case with Paula Zahn, that he posted bail prior to knowing his brother had abused Michelle. Hal later said he had promised the family he would post bail and would not renege on his promise. Investigators from Florida and Ohio also discovered Hal had withdrawn US$7,000 from his bank account at the time of the disappearance, which he was able to account for. He had planned to use it
