This as "The Los Angeles Times" has gotten ahold of some documents from a county, not the same county where Prince lived, but one county over that say the day Prince died, that they interviewed the people who were here. One of those people was a local doctor who actually showed up at the scene with test results for Prince because he had seen Prince twice before in April, including the day before Prince died. We have reached out to the place where this doctor is employed. They say that he is no longer, but they are investigating this further.
