Percy Miller, also known as Master P, is a hip-hop icon who has built an empire, owning and investing in everything from record labels and clothing lines to real estate, restaurants and a food line. He is also a father of nine children, and in May, his daughter Tytyana died. This week, the Los Angeles County medical examiner determined the cause of a death was a fentanyl overdose. Master P is now dedicated to speaking out about mental health and drug use in the hopes it will help other families.
