“The families and the community deserve that closure and we want anybody that has information to come forward,” Scott told WJZ. “This money means that we value the lives of our first responders, of our heroes, that literally gave the ultimate sacrifices for our city.”

“It’s like family in the first responder family, so there are a lot of intersections, not just in our region, but by those who have been affected by this tragedy,” Olszewski told WJZ. “We wanted all of the region and all of our own first responders to know that we are stepping up on behalf of them so that we can really bring this perpetrator to justice for this awful act. 

Fire crews were initially called to the scene of a two-alarm fire at a row home in the 200 block of S. Stricker Street about 6 a.m. Monday, according to the Baltimore City Fire Department.
