Master P's daughter  Tytyana Miller died on May 29th at age 29.

P was upfront with what he believed killed his daughter, who has a history of struggles with substance abuse.

"Our family is dealing with an overwhelming grief for the loss of my daughter Tytyana," he typed on Instagram. "We respectfully request some privacy so that our family can grieve. We appreciate all of the prayers love and support. Mental illness & substance abuse is a real issue that we can’t be afraid to talk about. With God, we will get through this. #MyAngel."

Police have confirmed P's suspicion that Tytyana's death was an overdose after finding drug paraphernalia at the scene.

The cops didn't uncover any drugs, so they will have to wait a couple of weeks for the toxicology report to narrow down what killed her.  When they figure that out, police will pursue whoever sold the drugs to Tytyana criminally.

RIP.
