On the evening of January 11, 2015, 63-year-old Henry Nunn answered a knock at his Indianapolis home and was fatally shot. The assailant’s identity and the motive remain unknown, and the Indianapolis Metropolitan Police Department lists the case among its unsolved homicides with no arrests announced.

Nunn had retired after forty years at Valspar Coating. He was married to Patricia for twenty-nine years and was a father and grandfather. Active in his church as an usher and well known in his neighborhood for hosting barbecues, he was described as having a big heart and an infectious smile.

News accounts have noted a theory that Nunn may have been targeted because he cooperated with police in a separate murder investigation, a possibility investigators have considered while pursuing leads.

Did anyone in Indianapolis know Henry or have information about who might have knocked on his door that night?
