From the London Mirror:
Cole Tomas Allen, 31, has been identified as the suspect after shots were heard outside a ballroom containing 2,500 people – including Donald Trump, Melania Trump and JD Vance – for the annual dinner. The US President described the suspect as a “lone wolf whack job” after the incident around 8:35pm local time (01:35am UK time) on Saturday night, at the Washington Hilton hotel.
Allen was carrying a 12-gauge shotgun, a .38-caliber handgun, and multiple knives. Video footage captures the moment a gunman charged a Secret Service magnetometer screening area in the hotel lobby. He discharged at least one shot, hitting a Secret Service agent’s bulletproof vest.
