“He kept avoiding questions. I kept getting mad,” Tyka said. “I felt like, ‘Talk to me for two seconds.’ He’d change the subject, make a joke and then we’d both laugh. He asked me could I find more information about our family. Prince wanted me to find [half-sister] Sharon’s number. I didn’t question it. It was like, ‘Send this picture to that person.’ OK. What for?”

Tyka and Prince also had five half-siblings: Sharon, Norrine and John Nelson (who died in 2021), Alfred Jackson (who died in 2019) and Omarr Baker.
