College students, older adults and officers dropped everything to give blood after the crash, said Rebekah Bell, a local resident.

“The Blood Assurance staff made sure that everyone was comfortable, and had a snack and drink before and after giving,” she said. “Most staff had been working since 7 a.m. and were still going as long as people wanted to donate.”

Although lines are long, Blood Assurance is fast-tracking people with the blood type O negative, according to Bell.

The blood bank has also extended its hours from 8 a.m. to 7 p.m. at three locations. Spokeswoman Mindy Quinn said that “hundreds and hundreds” of people have flocked to give blood.

In response to the tragedy, many residents are channeling their grief into generosity.
