Las Vegas police are getting closer to finding an explanation for why a gunman carried out the deadliest mass shooting in modern U.S. history, the city’s police chief said on Wednesday, as he defended the speed of the department’s response to the massacre.
Clark County Sheriff Joseph Lombardo, who oversees the police department, told the Las Vegas CBS television affiliate in an interview that police officials were not trying to cover anything up a day after revising the timeline for the shooting.
