Las Vegans flooded blood banks after tragedy struck their city, waiting outside facilities in hopes that they can help some of the hundreds wounded in the Route 91 festival mass shooting.
A line at the United Blood Service in the city was out the door at 4 a.m. on Monday, the morning after a gunman opened fire from the Mandalay Bay Resort and Casino, according to KTNV.
Some waited for hours until the facility opened, the station reported.
At least 50 people were killed, with the massacre appearing to be the deadliest mass shooting in modern U.S. history.
More than 400 people were also taken to the hospital with various injuries, according to police, leading to a sudden and massive demand on the city’s blood supply.

The goodness of people willing to donate has become a grim ritual after mass shootings, with hundreds of people in central Florida lining up last June to help those wounded in the Pulse nightclub attack.
