Lisa Wheeler-Brown hugs a well-wisher on Wednesday after a news conference to kick off Everytown, a political initiative to end gun violence that was held at St. Petersburg City Hall. Wheeler-Brown, who lost her 21-year-old son to gun violence, is an Army veteran and a gun owner. She was a speaker at Wednesday's event. "If I can prevent one mother from losing her child to gun violence, that is what I will do," she said.
