"You don't think about this in Tallahassee and now you have to", said Welling, 26, who lives in the neighbourhood.
Tallahassee Mayor Andrew Gillum, a Democrat who is running for governor, tweeted his appreciation to law enforcement for their response to the shooting, and said that he would be breaking off the campaign trail and was returning to the city Friday night.
