BTK serial killer investigation: new clue unlocks missing 16-year-old girl’s name

After receiving a word puzzle, Oklahoma police say they’re closer to identifying another victim of prolific murderer Dennis Rader

A newly re-examined word puzzle sent to a Kansas City TV station in 2004 could strengthen leads in a cold case investigation into the disappearance of a 16-year-old girl in Oklahoma and link it to imprisoned serial killer Dennis Rader, who was nicknamed BTK for “bind, torture, kill”.

At a news conference on Tuesday, Osage county sheriff Eddie Virden told reporters that he’d received a package from a woman in April containing a crossword puzzle that Rader used to taunt investigators.
