Tiffany Church, 35, and her boyfriend, Trodarius Rainey, 26, went missing Dec. 30. Their car was found abandoned on New Year’s Eve with at least one bullet hole, Seminole County Sheriff Dennis Lemma told reporters at a news conference on Wednesday. Investigators believe the assailants knew the victims, the sheriff said. He added that detectives have “a pretty good idea of what happened,” and are continuing to gather evidence. The sheriff said preliminary evidence shows that Church and Rainey were killed and then their bodies were dumped in different places.
