Former Boyfriend Held in Connection With Assault

Police have taken a man into custody in Antigua in connection with the assault, though authorities have not confirmed formal charges at this time. Johannsen’s sister told local reporters that the man in custody is her former boyfriend. The case is being actively investigated by the Royal Police Force, and authorities have appealed for anyone with information to contact their Criminal Investigations Department.

Wisconsin Community Mourns Loss

Johannsen was well known in her hometown as the daughter of the former owners of Johannsen’s Greenhouse, a longtime community business in Madison that operated for 50 years before closing in 2013. While living in Antigua, she often shared videos and photos of her horseback tours along the island’s beaches, reflecting her deep connection to local tourism and equestrian life.

Police have extended condolences to her family and urged the public to come forward with any information that might help clarify the circumstances of the attack. The investigation is ongoing, and further updates are expected as authorities continue their inquiries.
