The West Allis man arrested in connection with human remains found in two suitcases is being held in the Walworth County Jail.
Walworth County Circuit Court officials say the 52-year-old man is expected to appear in court Friday. He's being held on two counts of hiding a corpse.
The county's district attorney, Daniel Necci, says formal charges are not expected Thursday because he hasn't yet received the case from investigators.
The private security officer was arrested Wednesday when detectives wearing hazmat suits removed bags of evidence and a refrigerator from his suburban Milwaukee apartment.
Authorities say the remains of 37-year-old Laura Simonson, of Farmington, Minnesota, and another unidentified female were found June 5 in two suitcases discarded along a rural road in the Town of Geneva.
Police are asking for the public's help to identify the second victim, described as a possibly Caucasian woman, between the ages of 15 and 35, standing 5-foot-2 to 5-foot-4 and weighing 120 to 140 pounds.
She has long straight, dark brown or black hair, police said, as well as a pronounced overbite and crooked lower teeth. She also has two piercings in each ear and a quarter-sized heart tattoo on her lower left abdomen/pelvic area.
Anyone with information about the incident or identification of the second woman is asked to contact the Town of Geneva Police Department at 262-248-9926.
