GENEVA, Wis. - Wisconsin police have arrested a 52-year-old man almost three weeks after human remains were found in suitcases, and investigators identified one victim as a missing Minnesota woman.

Detectives wearing hazmat suits removed bags of evidence and a refrigerator from the suburban Milwaukee apartment of a former West Allis police officer..

Town of Geneva police Chief Steven Hurley said in a statement the man was arrested Wednesday.

Hurley says one of the victims was Laura Simonson, a 37-year-old from Farmington, Minnesota. Her mother reported her missing around Thanksgiving. Police say Simonson was a vulnerable adult whose family was worried about her mental stability. Her father, Richard Wierson, tells the Journal Sentinel that the Farmington, Minnesota woman struggled with mental illness and that he has cared for her seven children since 2010.

The other female victim hasn't been identified. Police say she appeared to be between the ages of 15 and 35, with a quarter-sized heart tattoo on her lower left abdomen.

Highway workers found the two suitcases June 5 in the Town of Geneva, about 50 miles southwest of Milwaukee. There was one body in each.
