Bombshell new video from Trump assassination attempt shows eerie figure running across rooftop minutes before shots rang out

Chilling video taken by one of the victims of the assassination attempt on Donald Trump shows a shadowy figure running across a rooftop moments before the former president was shot.

The haunting clip was taken by James Copenhaver who, moments later, was himself critically injured in the shooting in Butler, Pennsylvania on July 13.

In the footage, obtained by Fox Digital, the figure appears briefly on a roof overlooking where Trump was being cheered by his rally crowd. 

He appears to look towards Trump before running further along the roof. At the same time, Trump turns and is almost looking directly at his would-be assassin before he runs away.

Three minutes after the bombshell video was taken Thomas Crooks, 20, unleashed a hail of eight bullets, hitting both Trump and Copenhaver.

Heroic firefighter Corey Comperatore, 50, was killed while trying to shield his family during the attack.

Copenhaver, 74, sustained 'life altering injuries' but has recently been released from hospital. 

He is still recovering at a rehabilitation center, according to his attorney, who said he was hit in the arm and abdominal area. 

'He had almost seen or heard something whiz past him, which we're assuming was a bullet,' attorney Joseph Feldman said.

'He felt it on his arm, and he looked down at his arm…and felt pain initially, but he hadn't even realized he had been shot a second time at that point. It could have been shock.'

David Dutch, 57, was the fourth person injured and was reportedly shot twice and has undergone two surgeries.

Crooks was killed by a Secret Service sniper but major questions remain over the security breaches which allowed him to carry out the attack.

The lone gunman was identified as a suspicious person prior to the shooting and was seen wandering around the event site in the hours before. 

Disturbing video shot by someone in the crowd appears to show Crooks stalking around a building he would climb 60 minutes later in order to get the perfect vantage point from which to target Trump. 

He managed to get onto the AGR building roof by climbing HVAC equipment and piping and hopping travelling along several roofs, according to the FBI. 

Police were aware of a suspicious individual near the rally site around 90 minutes before the shooting began and snapped photos of Crooks at the scene. 

Secret Service Director Kimberly Cheatle was forced to resign amid the backlash over the blunders.

The FBI is still trying to investigate Crooks' motive. A classmate told DailyMail.com he had previously been investigated over threats to 'shoot up' his school when he was aged just 15.

FBI Director Christopher Wray has cast doubt on whether Donald Trump was actually shot during the attempt on his life at a Pennsylvania political rally

The incident was not taken seriously at the time but is now being probed by the agency. 

In his first interview following the assassination attempt, Trump said he survived 'by luck or by God'.
