Community activist Andrew Holmes had two messages for the group that gunned down a Chicago police officer and Iraq War veteran: "You didn't gain anything," and "We're looking for you."
By Thursday night, only one of those messages remained true.
Just hours after a pair of vigils held in Thomas Wortham IV's name, Chicago police announced they had a fourth -- and believed to be the final -- person in custody. No charges have yet been filed.
Wortham was gunned down Wednesday night by a group of people who tried to steal his motorcycle during a late-night visit to his parent's house. His father, a retired Chicago cop, fired back at the robbers, killing one of them and critically injuring another.
A third -- a 20-year-old Marquette Park man with a minor criminal record for a gun charge -- turned himself in Thursday afternoon at the Harrison District police station, officials said.
Holmes heads up the community group "No Guns, No Violence" and told the crowd of supporters and bikers gathered outside the District 7 police station at 63rd and Bishop that violence around the city must be snuffed out.
"We're not going to stand for too much violence in the streets of the city of Chicago. This is not a warzone and we're going to put an end to it," he said.
Wortham was a three-year-veteran of the Chicago Police Department, working in the Englewood District, and had purchased the motorcycle as a gift to himself after serving two tours of duty in Iraq.
He was active at the Nat King Cole park across the street from where he was slain, served on the park's advisory council and was vocal about the violence in the city.
"Thomas was a good person, a hardworking person, a person that works the streets and tries to enhance the quality of life for others out here," said Holmes.
