officer. We're going to keep you posted on this. Breaking news as we learn more. Also tonight, remember this bizarre mess on 880 in Oakland? A couple of weeks ago? Animal parts. Those are animal parts. Meat all across the freeway. Senior investigative reporter Bigad Shaban has been digging into the company that caused that traffic jam, and found that company has a history of leaving behind similar spills. A warning for you right now. Some of the video you're about to see is disturbing. Bigad Well, when it comes to that grisly gridlock, it turns out while the meat was rare, the mess was not. We've learned the company responsible has been repeatedly blamed for other gory accidents, which means Oakland isn't the only one with a beef. There is no mincing words about four lanes full of minced meat. The highway spill in Oakland along I-80 caused four separate accidents and backed up traffic for hours. By the time we got over here, it's just like gridlock. Nothing moving. But who caused the disgusting mess remained a mystery until now. A truck from Darling Ingredients spilled piles of raw poultry, according to law enforcement. The company runs a large plant in San Francisco and turns animal parts into fertilizer and fuel. The California Highway Patrol tells us, by law, the driver should have pulled over after the spill, but kept going anyway. The company wouldn't answer many of our questions, but in a statement said it launched an internal investigation and is cooperating with all relevant authorities. CHP says the whole mess is still under investigation. But we've learned darling Ingredion has made headlines before for leaving similar trails of animal remains in new Jersey, Virginia, Canada and repeatedly in Clinton, North Carolina. This is not an easy cleanup. Anthony Davis is the police chief for the small agricultural town of Clinton. About 60 miles south of Raleigh, North Carolina. The city is a frequent pass through for truck drivers, making deliveries for darling ingredients. The chief says his city has been forced to clean up at least a dozen of the company's roadway spills just over the past two years. What kinds of messes have you had to deal with? Blood, guts, leftover feces, hog parts, legs? Heads? We've seen a little bit of everything. Chief Davis says darlings, drivers were leaving the scene so often he pushed politicians to pass a new state law allowing his city to levy criminal charges against those who leave the scene of grisly messes. The law has only been in effect for about six months, but the chief says two truck drivers from Darling Ingredients have already been criminally charged for new spills. We were able to locate the truck in a neighboring county, basically followed the trail of blood. And be honest with you. The chief says in his area, trucks for darling ingredients transport animal parts in open top trailers only covered by tarps. We checked out the trucks going in and out of the darling facility in San Francisco and saw this same setup tarps draped over storage containers. Whether they're slamming on brakes going around a curve too fast, it just comes over the side of the trailers and now it's on our roadways. What does it tell you? That even after everything your town has been through with these kinds of messes, there was just a recent one here in California. I think he just goes to show that we're not making any progress. We've learned Darling Ingredients and its subsidiary companies have been hit with at least 27 violations throughout the country for overfilling their vehicles just during the past year, according to federal transportation officials. At least a dozen other violations were also issued for failing to properly secure cargo. And then there's the smell that lingers. It'll be weeks and weeks at a time. If the spill is pretty big, it's horrible. And you'll never forget the smell. You haven't I haven't absolutely not . And even for those in the Bay Area used to never ending traffic jams getting stalled by mounds of meat on the freeway still proved to be
