Boca police detectives recently obtained an arrest warrant for Richard Allen Mingst, 70, for sexual battery on a minor and possession of child pornography. A family member who found pornographic images of Mingst and a child on his digital camera first alerted detectives. The acts occurred in Mingst’s Boca Raton condominium, and he was arrested at his home in Blue Ridge, Ga. He is currently awaiting extradition to Palm Beach County and also faces charges in Georgia.
