After his neighbor identified handwriting samples placed on local billboards by police, Oba Chandler was arrested three years after he committed a triple murder in the Tampa Bay area in Florida.

Oba Chandler Jr. was an American mass murderer, rapist, robber, and fraudster who was convicted and executed for the June 1989 murders of the Rogers family, consisting of Joan Rogers and her two teenage daughters Michelle and Christe, whose bodies were found floating in Tampa Bay, Florida, with their hands and feet bound. Autopsies showed the victims had been thrown into the water while still alive, with ropes tied to a concrete block around their necks. The case became high-profile in 1992 when local police posted billboards bearing enlarged images of the suspect's handwriting recovered from a pamphlet in the victims' car. Chandler was identified as the killer when his neighbor and three people that were suing him recognized the handwriting.
