The federal police FBI has accessed the phone belonging to Thomas Matthew Crooks, who shot at the US's former President Donald Trump at a campaign meeting over the weekend. This is stated by the authorities in a statement.
The phone had been sent to the FBI's lab in Quantico, Virginia, for examination, but so far it has not provided more information about a possible motive or political ideology, according to American media. The investigators have only found traces of activities such as an interest in computer games and computer programming.
The shooting is being investigated by the FBI as an attempted murder of the Republican presidential candidate Donald Trump, who was injured in the ear, and possible domestic terrorism.
Two people, including Thomas Matthew Crooks, were killed and two were seriously injured in the attack.
During the 48 hours before he opened fire on Donald Trump, Thomas Matthew Crooks made several stops in his hometown in a suburb of Pittsburgh, according to CNN, which has mapped the shooter's last days in life.
On Friday, he visited the shooting club where he was a member and practiced shooting. The next morning, he went to the retail chain Home Depot, where he bought a ladder, and to a weapons store, where he bought 50 magazines with ammunition.
Then the 20-year-old drove his Hyundai Sonata an hour north, to Butler, Pennsylvania, where thousands of people had gathered to see Donald Trump's campaign speech. He parked his car outside the campaign meeting, with a homemade bomb in the trunk, which was connected to a trigger that he took with him, according to information to CNN. Then he is believed to have used his newly purchased ladder to climb up a building and open fire on the former President.
