On Tuesday, Thomas Turley, a youth worker from R City, described Ms Ferris as a “great character”.
She was a member of the organisation when she was a teenager and Mr Turley said she “brought a lot to the group”.
“You could tell from the outset that she was a leader in and amongst the group and how much her peers looked up to her,” he told News NI.
“She had great drive and enthusiasm about her and that was something that always shone through along with how bubbly she was and how fun she was to have about.”
Mr Turley said the group was thankful to have someone like Ms Ferris involved in the programme and she left a legacy with the people there.
“The outpouring on social media just shows how much of an impact Chloe made right across the community and everyone she came into contact with,” he said.
