Following an autopsy performed by Dr. A. Quinn Strobl, a protege of Janis Amatuzio, his remains were cremated. On April 26, 2016, Prince's sister and only full sibling Tyka Nelson filed court documents in Carver County, to open a probate case, stating that no will had been found. As of his death, the twice-divorced Prince was neither married nor known to have fathered any surviving children. Under Minnesota law, in the absence of a will, this meant that, in addition to his full sister, Prince's five half-siblings also had a claim to an estate totaling millions of dollars, and including real estate, stocks, and cars. Within three weeks of his death, 700 people claimed to be half-siblings or descendants. Bremer Trust was given temporary control of his estate, had his vault drilled open, and was authorized to obtain a blood sample for DNA profiling from the coroner who had performed the autopsy.
