A gunman opened fire Monday outside the largest casino in Reno, Nevada, killing three people and wounding three others before being taken into custody, officials said. Two victims were in critical condition, while the other had been released from the hospital, Sparks Police Chief Chris Crawforth said during a news conference Monday. The suspect had no known connection to the victims, police said, adding that the motive is unknown. The shooter walked up to the casino-hotel’s valet parking area, pulled out a handgun and pointed it at a group of people, police said. His gun initially malfunctioned, but he quickly was able to get it to shoot. The suspect fled on foot through the parking lot where he encountered an armed casino security guard. Crawforth said the gunman opened fire on the guard, who returned fire as the shooter fled. The suspect also shot at someone driving by in the parking lot, striking and killing the driver. Officers arrived less than three minutes after the first shots rang out and fired at the suspect, police said in a statement. The resort is one of Reno’s most prominent venues, hosting concerts, sporting events and a campaign rally by President Donald Trump before the 2024 election. Near the California border and just northeast of Lake Tahoe, the town is a popular summer tourist destination. Hours after the shooting, the entrance inside the casino leading to the valet area was roped off to guests and privacy screens were placed in front of the glass doors to block the view outside. In addition to those who were killed and the people taken to the hospital, three more were treated for minor injuries at the resort, according to Devon Reese, chair of the Board of Health in northern Nevada. One person was grazed by a bullet on their pinky finger, one was treated for severe anxiety and one was injured while running, he said. More than a year ago, two men were charged with fatally shooting another man who was staying at the resort in January 2024. The Grand Sierra claims to have the biggest casino floor in northern Nevada and sits just a few blocks from the Reno-Tahoe International Airport. It’s also one of the tallest buildings in the city, with nearly 2,000 hotel rooms.
