Detective Hopes Zodiac Film Prompts New Leads In Dead Case

The California detective who headed the chase for the mysterious Zodiac Killer 35 years ago is hoping a new movie about the investigation will prompt new leads - because he's still haunted by the case he couldn't solve.

Dave Toschi, who is played by Mark Ruffalo in director David Fincher's new thriller Zodiac, still marks the anniversary of the San Francisco serial killer's first murder by revisiting the crime scene in Presidio Heights.

But he reveals the case is as cold as ever and was marked inactive in 2004.

Toschi only hopes that by this year's ill-fated anniversary in October, the identity of the killer will be known - thanks to the film.

Toschi, who became the model for San Francisco cops played by Steve McQueen in Bullitt and Clint Eastwood in the Dirty Harry movies, says, "I make it a point to cross that intersection of Washington and Cherry all the time, especially every anniversary. A lot of times I go and stop and think about it, the prints and the blood. I just stop to see if maybe somebody else would be parked there, maybe the killer would show up. I was always trying to figure out 'Where did we go wrong?' It's never left me."
