What Was He Trying to Text Before He Was Murdered?

Joey LaBute, 26, disappears after leaving a bar in Columbus, Ohio. Three weeks later, fishermen find his body in a local river. But he didn’t drown. He was dead before he went into the water. And he left behind two cryptic clues: In a call, he told a friend he was “driving” but he wasn’t in his car. And his final text was a string of strange letters that could have been a clue to who killed him. Can you make sense of the text?
