INDIANAPOLIS (WISH) – News that Prince Rogers Nelson died this week shocked music fans and the public alike.

Authorities said Friday that while an autopsy was performed, no cause of death has been determined.

Authorities discovered the 57-year old musician unresponsive in an elevator of his estate and studio in Chanhassen, Minnesota on Thursday. Coverage of the musician’s death has been dominated by discussions about what may have killed the prolific singer-songwriter. There have been published reports that the rock star was hospitalized within the past week and that he was seen at Minnesota drug store hours before he died. Police announced Friday that they are still actively investigating the circumstances surrounding his death.

Most of the conversations about Prince’s legacy have been about his music, his religious journey, how that influenced his music and – as of late – his charitable giving.

I-Team 8 found federal tax records that show one of Prince’s charities, Love 4 Another Charities, has donated millions of dollars to schools, shelters and community programs in Los Angeles, New York, Chicago, his native Minneapolis and even Ames, Iowa. The three years worth of tax records reviewed by I-Team 8 show no donations to facilities in Indiana, but the scope of the records viewed was minimal.

Contributions also were given to organizations, schools and facilities in Georgia, Texas, Wisconsin and Ohio.

Prince’s signature can be seen on the tax forms for his non-profit charity, which are public record and available for inspection.

The 2007 filing for Love 4 Another Charities shows the organization – at the time – had more than $11 million in assets – much of that was cash.

Prince noted in the records that he spent about five hours a week working on the charity.

The news website Insider Louisville published a report Friday that Prince had given a $12,000 donation to a public library in Louisville in 2001. The singer had asked that the award be kept silent but the online news organization was able to confirm the story that included a picture of the check.
