New Delhi, July 14 (IANS) Thomas Matthew Crooks (20) has been identified as the person suspected of shooting former US President Donald Trump in an attempted assassination, the FBI said in a statement. "The suspected shooter was Thomas Matthew Crooks (20) of Bethel Park, Pennsylvania, as the subject involved in the assassination attempt of former President Donald Trump on July 13, in Butler, Pennsylvania," said the FBI. Crooks was killed on the spot by the security officials after he fired shots at the former US President, piercing through his ear, during a campaign rally in western Pennsylvania. The FBI had earlier said that the shooting was being investigated as "an assassination attempt" on Trump. The motive behind the assassination attempt, however, is yet to be revealed. Trump, who is due to be anointed the Republican Party's Presidential candidate, had a narrow escape on Saturday when shots aimed at him at a campaign rally grazed his right ear and killed two people at the event. --IANS
