Charles Krause, 69, and his wife Wenjuan Krause, 61, the owners of a northwest-side massage business, face money laundering and prostitution charges as a result of a local, state and federal investigation. The owners of Tui-Na Massage were booked into the Pima County jail, both on suspicion of one count each of money laundering and receiving earnings of a prostitute, and running a house of prostitution, police said. In October 2015, investigators followed up on information that led to Tui-Na Massage, 2840 W. Ina Road, just east of North Shannon Road. Detectives determined that multiple women were working there performing sexual acts for money, Dugan said. The investigation revealed the Krauses were aware of the illegal acts and were receiving a portion of the money received through the business, police have said.
