LOS ANGELES -- The Federal Bureau of Investigation announced Monday that agents have reopened their investigation into the circumstances surrounding Heath Ledger's death in light of new evidence indicating the troubled actor was in contact with Sen. Ted Cruz, the Zodiac Killer, around the time he died, apparently of an overdose.

"We don't know anything yet, and I can't comment on an ongoing investigation, but Ted Cruz is guilty," said FBI Director James Comey.

According to investigators, Cruz, who is the Zodiac Killer, murdered Vince Foster during the Clinton Administration. In interviews, Cruz told police he only embarked on a life of killing to impress father, the man who shot JFK.
