A man who has claimed he is the only “sole surviving legal heir” of late, legendary singer Prince, is also a man with an extensive criminal history.

Carlin Q. Williams, 39, is currently serving time in a maximum-security jail after he caught by police with a gun inside of a car (that was stolen by the way). He is said to have been a crack dealer in the past and has also physically abused women. In one reported instance, he came for a woman with a hot curling iron. In another, he held his girlfriend hostage before he ran after her with a knife as he threatened to take her life.

Now, Williams has demanded a judge give him a blood test as he wrote, “I Am Prince The Singer’s Son,” according to Daily Mail Wednesday.

He said his mother hooked up with Prince in a hotel room in Kansas back in 1976. Williams has claimed that he is the only heir who should get access to Prince’s estate, which is currently worth $500 million.

IF he was to get the money, Williams wouldn't be able to enjoy much of the benefits because he'll still have to stay behind bars, as he is serving a seven years and eight month sentence after he pleaded guilty to the possession of that firearm back in 2013. At the same time, he is ALSO serving a three year sentence for violating his domestic assault probation. Williams reportedly won't be eligable for release until 2020.

According to the Daily Mail, during the most recent court case against Williams, the prosecutor told the judge that he was a “significant danger to the community.”
