In the wake of a shooting in El Paso, Texas, that left 20 dead and dozens more injured, people wasted no time heading to blood donation centers and stood on line for hours for the chance to help.
Hours later, another community was left reeling in the wake of a mass shooting, after a deadly rampage in Dayton, Ohio, in the early hours of Sunday morning.
Officials in both communities are asking for help from the public, though in slightly different ways.
Dayton is still just hours removed from the shooting, so more specific ways to help remain largely in the works.
For now, though, police are calling for witnesses to reach out with any and all tips regarding the shooting, which took place just after 1 a.m. local time.
They have launched a family assistance center for friends or relatives of possible victims to gather and receive information.
