Chisholm has not cooperated with detectives on what led to the incident and they are continuing to gather information.
Friends of Colon said she had recent health problems and used an oxygen tank to help with breathing. She planned to meet a friend on Monday to pick up a tank and when she didn’t show up, friends became concerned, an acquaintance, Dave Groveman, said.
Colon was a member of the social group Celebrate Atlanta where Groveman is group organizer. He described her as a small person in stature but feisty.
“Marlene was sweet and perhaps too nice,” Groveman said. “She had a new boarder but she’s had troubles with tenants in the past. She had one removed for not paying her.”
Members of Celebrate Atlanta are discussing raising funds to place a bench plated with Colon’s name in a local park, Groveman said.
