On Monday, news broke that at least 59 people had been killed and more than 500 injured in a mass shooting at a Las Vegas concert. By Tuesday morning, a GoFundMe page called "The Las Vegas victims fund" had already raised more than $3 million.
The page, created by Las Vegas Clark County Commission Chair Steve Sisolak, had an original goal of $500,000. After an immediate outpouring of support, Sisolak raised his goal and the new one was also surpassed.
Sisolak donated $10,000 of his own money to the campaign, saying via Twitter, "I'm overwhelmed by the outpouring of support from the Las Vegas community [and] beyond. We need more donations, every penny will be put to use."
He and other officials are also calling for blood donations.
The suspect, identified as Stephen Paddock, 64, was found dead in his Mandalay Bay hotel room Monday in an apparent suicide.
The attack targeted more than 22,000 people and has been called the deadliest mass shooting in U.S. history. American singer Jason Aldean, who was performing at the time, responded on Instagram.
