In a separate incident Sunday, a heavily armed man was arrested in Southern California even as Mateen's attack was ongoing, telling police he was going to a gay pride parade. Twenty-year-old James Wesley Howell of Indiana, had assault rifles, ammunition and chemicals that could be used to make an explosive, according to police, who said there was no evidence of a connection to the Orlando massacre. Santa Monica Police Chief Jacqueline Seabrooks initially tweeted that Howell said he wanted to "do harm" at the event, but she corrected her statement to say only that he said he was going there.
