LOS ANGELES: Authorities in California said on Sunday they were trying to piece together the motive of a man who had an arsenal of weapons in his car and planned to attend the Los Angeles Gay Pride parade. James Howell, 20, was arrested at around dawn in Santa Monica with multiple weapons, ammunition and bomb-making materials in his car, which had Indiana license plates, police said. The arrest came just hours after 50 people were massacred at a gay nightclub in Florida, prompting fears of a similar attack in Los Angeles. Santa Monica police chief Jacqueline Seabrooks initially said that Howell told the arresting officers that he wanted “to harm” the annual L.A. Pride parade taking place in Hollywood on Sunday.
