The family of Kaia Sealy, who was shot three times by police during an incident in St Augustine last month, has launched a public fundraising drive to help cover her mounting medical and rehabilitation expenses.

Sealy, a young mother, is paralysed from the waist down following the January 20 shooting which claimed the life of her husband, 31-year-old Joshua Samaroo.

According to the family, a fundraiser has been established on the GiveSendGo platform with a target of $500,000 to assist with specialised medical treatment, rehabilitation, mobility support, transportation to medical appointments and basic living expenses for Sealy and her five-year-old daughter.
