A timeline released by Las Vegas police earlier this week led to concerns they didn't do enough to prevent the Oct. 1 shooting that killed 58 people and forced the owners of Mandalay Bay to release a statement openly disputing the timeline, the AP reports. Metro Police had said Stephen Paddock fired 200 rounds into the hotel hallway, injuring security guard Jesus Campos, at 9:59pm—about six minutes before he opened fire on a music festival 32 floors below. Clark County Sheriff Joe Lombardo says that timeline led to characterizations of the police response as "incompetent," which "absolutely offended" him. And MGM Resorts International released a statement Thursday saying at most 40 seconds passed between when Campos was shot and when Paddock opened fire on festivalgoers, according to the Las Vegas Sun.
On Friday, Lombardo said a new timeline by police is "not in conflict" with the MGM statement, NPR reports. He said Campos was shot just about the same time Paddock opened fire on the festival. The original 9:59pm time was actually when Campos found a barricaded door on the 32nd floor of Mandalay Bay, Lombardo said. This is not the first time the timeline of the shooting has changed—officials originally said Campos was shot after Paddock started firing on the festival—and Lombardo warned it could still change again. Lombardo also increased the number of injured from 489 to 546, with 45 still hospitalized. The biggest questions remain: What was Paddock's motive and why did he stop shooting? Lombardo said police arrived at Paddock's room 12 minutes after he shot Campos, but the festival was only under fire for 10 minutes. (Read more Las Vegas shooting stories.)
