Officers say they confiscated over $37,000 worth of drugs from a Marshalltown home this week.
Officers arrested 27-year-old Helle Neville, 29-year-old Kari Gavagan and 63-year-old David Robbins Monday morning.
Police and the Mid-Iowa Drug Task Force served a warrant at their home in the 300 block of West State Street. They seized a half a pound of meth and two pounds of marijuana along with $4,000 in cash and other packaging materials.
The case remains under investigation and authorities expect more arrests in the case.
