In 1974 Charles left the Indianapolis Police Department to continue his studies in criminology at Indiana University.  Since he had previous training in voice stress analysis with the original voice stress analyzer, the Psychological Stress Evaluator, and because of his expertise, Charles quickly became a consultant to law enforcement, private business, and prosecutors throughout the Midwest.

It was also during this time that Charles founded the Sonshine Inn, a Christian coffeehouse ministry located at 33 S. Arsenal Ave, Indianapolis, IN, devoted to helping intercity youth find a new meaning to life and follow a new, successful direction.  Over the eight years that Charles served as the Founder and Director of Sonshine Christian Ministries, literally hundreds of lost young people were lifted from a life of certain desolation to becoming productive members of society.  With a volunteer staff of 32, the Sonshine Inn became a beacon of hope in what for many was a dismal existence in the intercity of Indianapolis.  During this time Charles also toured as a percussionist with the Christian Jazz band Friends.  This followed many years with his own Christian Country-Rock bands: Firewind and Agape Union, where he was a guitarist and lead vocalist.
