Jason Aldean thanked fans for the outpouring of support and canceled three upcoming tour stops in a statement issued Tuesday afternoon (Oct. 3), two days after Sunday's mass shooting at the Route 91 Harvest Festival in Las Vegas.

They Don't Know Tour dates scheduled on Oct. 6 in Los Angeles, Oct. 7 in San Diego and Oct. 8 in Anaheim, Calif., have all been canceled. Aldean's tour will resume on Oct. 12 in Tulsa, Okla. Refunds for the three California shows are available at the point of purchase.

Previously, an executive at his record label had indicated they were undecided about how they'd handle upcoming show dates. Aldean was on stage singing his hit "When She Says Baby" when gunman Stephen Paddock opened fire on 22,000 country fans at Route 91 in Vegas. Fifty-nine people were killed and more than 500 were injured in the attack.

Read Aldean's full statement:

As a result of what happened in Las Vegas this week, we have decided to cancel this coming weekend's shows. I feel like out of respect for the victims, their families and our fans, it is the right thing to do. It has been an emotional time for everyone involved this week, so we plan to take some time to mourn the ones we have lost and be close with our family and friends. Our plan is to resume the tour the following week in Tulsa, Oklahoma. Our first time back onstage will be a very tough and emotional thing for us, but we will all get through it together and honor the people we lost by doing the only thing we know how to do - play our songs for them. I hope everyone understands why we can't play this weekend and I'm sorry if anyone is disappointed.

I want to say thank you for the outpouring of love from my friends and fans we have received over the last couple days. You guys have no idea how much you have helped get us through this tough time.
