Clearwater police are looking for witnesses to an eight-vehicle collision on U.S. 19 the evening of June 19 that killed two people. Daniel Barga, 27, of St. Petersburg was arrested Thursday after police say they discovered he was responsible for the collision. Barga initially told detectives that he was a passenger in the Chevy Avalanche that caused the crash and that the driver had run away. But investigators were able to determine that Barga was the driver, Clearwater police spokeswoman Elizabeth Watts said. Now, Watts said, investigators need additional information about what exactly happened that night. She asked witnesses to contact the Clearwater police Traffic Investigation Division at (727) 562-4119. Jancarlos Alberto Schaffer, 22, of Odessa and Richard Kelly of Tampa, whose age was unavailable, were killed in the crash. Seven others were hospitalized.
