One group of so-called "Helpful Hoodlums" is making sure those working through the aftermath of the Las Vegas shooting are not forgotten.
At first glance, they might be seen as taboo and scary. But they're actually making a big difference.
They call themselves the Helpful Hoodlums, on a mission to collect and deliver donations in the wake of Sunday's shooting.
"Literally anything that you can donate that you can think of will find a place for it," said Dustin Hoots of the Helpful Hoodlums.
These hoodlums are collecting toiletries, food and clothing and then packaging them for nearby fire departments, police stations and hospitals.
"We get to drop it off and see what everyone's going through and everyone's been really receptive and really thankful," Hoots said.
He started Helpful Hoodlums the night of the shooting as he and a few friends were shuttling victims who needed a ride.
"A lot of people don't have their money because they left it at the concert, so we start driving people from Thomas and Mack to their hotels and stuff," Hoots said.
Now setting up shot at Evel Pie on Fremont Street, the owner says these folks are exactly why you should never judge a book by its cover.
"They would see that they're tattooed up and think that they're just outcasts of society," Branden Powers said. "... But these are the guys that are stepping up, in the trenches and doing what they're doing and they're amazing."
If you would like make a donation to Helpful Hoodlums and become part of the group, you can stop by Evel Pie.
