FRESNO, Calif. (KABC) -- New shocking video shows Fresno police shooting and killing a 19-year-old man on June 25.Fresno police said they had responded to the call of a man walking with a rifle. While searching the area, officers said they spotted a truck speeding and tried to pull it over.Authorities said the driver, Dylan Noble, took off and led officers on a half mile chase.Noble pulled into a gas station parking lot and police said he refused to show his hands, and made a "conscious effort to conceal one hand behind his back, then in his waistband, as he exited the truck, and walked away from officers," according to a press release from Fresno police.Officials said Noble then said he "hated his life," turned around and walked toward officers. That's when police said Noble was shot.Authorities said Noble was shot a total of four times. In the video, two of the shots can be heard and seen. Noble appears to already be on the ground near or underneath his truck. There was a 14 second gap in between the two shots in the video.It was later determined that Noble was unarmed.Noble's parents have retained attorneys who were looking at the possibility of suing the police department. The shooting was also captured by police body cameras, but the department has refused to release it.But a witness, standing about 100 feet away, recorded cellphone video.The video is 26-seconds long. What the video didn't doesn't show, according to Fresno Police Chief Jerry Dyer, was officers confronting Noble for more than a minute while he ignored dozens of their commands and mimicked the movements of someone armed with a gun."When he gets within about 12 feet of the officers, he makes the statement 'I hate my effing life' and then he quickly starts to pull his hand out when the officer fires two rounds and shoots him," Dyer said.After those shots, Noble fell to the ground and the video began. It's difficult to make out what was happening as Noble was on the ground from the witness video, but Dyer said body cam footage from about 10 to 12 feet away painted a much more detailed picture."That happened twice, where he deliberately raised his shirt with the left hand and reached with his right hand underneath his shirt into the waistband," Dyer said. "The officers, at that point, believed he was trying to retrieve a firearm and they fired."Noble's friends and family have asked police to let the public see the video from the officer's perspective.But Dyer said the department wouldn't release the body camera video while the investigation was still ongoing."I believe it explains so much, but I believe it is premature," Dyer said. "I don't want to taint any potential witnesses."Dyer stated the last witness they knew of was the person who recorded the video and said the department could release the body camera video within the next couple months.Attorneys for Noble's parents called for an investigation by an outside agency such as the FBI.Dyer said last week that he asked the FBI and the U.S. Attorney General's office to conduct their own investigations and they agreed to take the case.
