Judge Authorizes DNA Testing of Prince's Blood

A judge has authorized DNA testing of Prince's blood.

Bremer Trust, the special administrator of the singer's estate, filed a new document today in Carver County, Minnesota, court that authorizes it to have Prince's blood genetically analyzed.

According to the document, which was obtained by ABC News, the testing will be "for any purpose relevant to the administration of the Estate." For example, if a potential heir comes forward, it will be possible to determine a blood relation.

Bremer Trust is authorized to hire DNA Diagnostics Center for the testing, and the Midwest medical examiner is authorized to release the blood sample for testing.

Prince was 57 when was found dead in his Paisley Park estate in Minnesota last month. A cause of death has not yet been released, though an autopsy was performed on April 22, one day after his death. However, results of toxicology tests are not expected back for some time.

Meanwhile, Prince's sister, Tyka Nelson, filed paperwork shortly after he died stating that she didn't think he had a will. As a result, Bremer Trust was appointed to manage the singer's estate.
