L.A. County Sheriff Jim McDonnell spoke Monday morning about the reaction of L.A. law enforcement to the Las Vegas mass shooting, saying that his department had stepped up its level of vigilance throughout the county.

McDonnell said his department would provide "a higher visibility of our folks, (and) a greater level of interaction with the public" in all venues that would draw large crowds coming together during a press conference at the Hall of Justice.

Late Sunday in Las Vegas, a gunman opened fire from a 32nd-floor room at the Mandalay Bay Resort and Casino and hit the crowd gathered on the Strip for the Route 91 Harvest Festival. As of Monday afternoon, Las Vegas Sheriff Joe Lombardo stated that at least 59 people were dead and 527 people injured in what is being called the deadliest mass shooting in modern U.S. history.

Many people living in L.A. have been affected by the shooting.

Since 10 p.m. Sunday, when the shooting was initially reported, over 2,000 posts containing content related to "Las Vegas Shooting" were released by social media users in L.A. Some of these posts expressed condolences to those who lost their lives.

McDonnell said that two employees from his department were confirmed to be shot and transported to local trauma centers while in Las Vegas. One was still in critical condition but stable as of Monday morning, he said.

In terms of how law enforcement in L.A. helped people affected by the shooting within and out of the state, McDonnell said that he reached out to Sheriff Lombardo of Las Vegas right after he heard of the shooting. His first thought, he said, was "whatever we have, let's offer them, and if we can get them the assets necessary to stop this, we want to be able to do it as quickly as we can."

"We've tried to facilitate that as best we can," McDonnell said. "We've been running back and forth throughout the night with both our air assets, as well as people driving over there. We were trying to accommodate the needs of anybody who needs help as it relates to being able to look out and take care for their loved ones."
