Karen Johannsen, a 66-year-old former Wisconsin store owner and local gardening expert known for her appearances on News 3 Now’s “Green Gardener” segment, was fatally attacked on December 19, 2025, while on a horseback riding tour in Antigua. She suffered a serious head injury after being struck by an unidentified male suspect, was initially treated at Sir Lester Bird Medical Centre, then airlifted to the U.S. for further care, but died a week later on December 26. Authorities have taken a suspect into custody who is cooperating with the investigation.

Johannsen was remembered fondly by her Wisconsin community for her work at her family’s garden center and her gardening expertise. It remains unclear whether she was residing in Antigua or visiting at the time of the attack, though her social media indicated she traveled there occasionally. Police have urged anyone with information to come forward to aid the ongoing investigation.
