Rochester, MN (KROC AM News) - Criminal charges are expected to be filed in the near future in the death of a woman who was apparently killed in Rochester more than a year ago.

Olmsted County Attorney Mark Ostrem says his office has finally received hundreds of documents from prosecutors in Wisconsin, where a murder case against 53 year old Steven Zelich is set to go to trial in May.

The case came to light when the remains of two women were found in suitcases along a rural Wisconsin road in June last year.One woman was later identified as a 19-year-old college student from Oregon. Zelich has told investigators she was killed in August 2012 while the two were at a hotel in Kenosha and he hid her body in a refrigerator for more than a year. The other woman was from Farmington, Minnesota.  It’s believed she was killed at a Rochester motel in November, 2013.

Zelich told investigators he killed both women after meeting them online through sex and bondage related websites. Zelich has told investigators the two women died during what he said was “ breath control play “ or erotic asphyxiation.

Zelich is a former Milwaukee area police officer.
