A US trucker who crashed into three police cars and two fire trucks, killing an officer, was looking at lewd images on his mobile at the time of the crash.
Jorge Espinoza was driving over 100km/h when he ran into the back of the parked vehicles in Yuma County, Arizona on May 6, the Star reported.
Officer Tim Huffman was trapped in the car he had been sitting in and died before he could be freed from the wreckage.
Espinoza initially told investigators that did not see the convoy because he was looking in his mirror at a passing truck.
However, data taken from his mobile phone revealed he was using the internet moments before the collision.
Espinoza was on Facebook looking at "photographs of several women in provocative positions, wearing little clothing", "photographs of a woman in a low-cut dress" and photos of a man "smoking something", according to the reports obtained today.
He had also used his phone to search female escort, pornography and other social networking websites when logged in as driving.
The report confirmed Espinoza, who has since been charged with second-degree murder, tried to cover up the fatal error after earlier released dashcam footage showed a phone flung from his hand in the crash.
Huffman was among 12 officers and medics at the scene responding to an earlier crash.
His colleagues pulled the windscreen and dash off the patrol car but were unable to reach him in time.
Six vehicles in total were destroyed in the pile-up.
