Someone was willing to pay money to have that person killed.Witnesses said tell Scripps News the scene was chaotic.Blood was everywhere, said Drew Hawkins, a reporter from Gulf States Newsroom, who was visiting town with his family on an unrelated journalistic assignment.Hawkins said he jumped out of bed when he heard the gunfire outside of his hotel. It was so loud...like multiple power drills blended together into one, monotonous drone of just unbelievably rapid-fire power.He said he could see people running and screaming for help, so he grabbed his gear and took photos and a video of the scene.Hawkins, who had enjoyed a walk in the same area with his family several hours earlier, said he counted multiple people, who appeared to be victims, laying on the ground.I counted at least six or seven people on the ground, and several of them were clearly deceased, he said.I could hear one gentleman who was standing next to me looking at a woman on the ground who was deceased saying, Thats my sister. My sister is dead, added Hawkins."It's difficult," Police Chief Scott Thurmond said Sunday morning. "Our heart is with the community."The police department, which is also investigating an unrelated quadruple homicide from July, solicited surveillance video from nearby businesses and tips from the community.When the public comes forward and shares information with law enforcement...the men and women work day and night, tirelessly, to get those cases solved and get those individuals off the street, said Thurmond.Gun violence is an epidemic crisis in our country, said Birmingham Mayor Randall Woodfin. The city of Birmingham finds itself, unfortunately, at the tip of that spear.
