When Pittsburgh police officer Calvin Hall was fatally shot trying to break up a neighborhood fight off-duty in July, many people felt helpless to do anything. Now there is something you can do to honor him, and support the Western Pennsylvania community where blood banks are running critically low on supply.

Officer Calvin Hall.

Pittsburgh Police have partnered with Vitalant Pittsburgh for a month-long blood drive in Officer Hall's honor. If you're able, police Chief Scott Schubert and Public Safety Director Wendell Hissrich are encouraging you to do like they did and roll up your sleeve:

You can donate any time, of course, but to donate in Officer Hall's name as part of this blood drive, you have until the end of August.

To make an appointment, visit vitalant.org/officerhall or call Vitalant at 412-209-7000. At the time of your donation, simply mention to staff that you are donating in Officer Hall's memory or mention the group code Z0021100. This code should be valid in Western Pennsylvania, Eastern Ohio, and West Virginia.

"Gotta go. Time for me to make a difference." Officer Calvin Hall

These are the words that Officer Hall would say before he started each shift. As the Bureau of Police wrote on their Facebook page : "He was all about making a difference in the community. We have the chance to keep Calvin's memory alive by helping others. Time for all of us to make a difference."

That's something we definitely agree with here at Sparkt.
