MILWAUKEE » A former suburban Milwaukee police officer pleaded guilty today to killing an Oregon woman and ditching her body in a suitcase along the same Wisconsin highway where he also is accused of dumping another woman’s body.

Steven Zelich pleaded guilty in the death of 19-year-old Jenny Gamez, of Cottage Grove, Oregon, whose body was found in 2014, though authorities believe she died in 2012. The plea deal was announced on the same day Zelich’s trial was set to begin.

Zelich pleaded guilty to first-degree reckless homicide with use of a dangerous weapon and hiding a corpse in the Gamez case, which is being handled in Kenosha County, about 40 miles south of Milwaukee.

The former West Allis police officer also is charged with killing a Minnesota woman, 37-year-old Laura Simonson, whose body also was found in a suitcase along the same highway. Authorities believe she died in 2013 in Minnesota, so charges in her death were filed in that state.

Kenosha County Deputy District Attorney Michael Graveley said he will push for the maximum 75-year prison term when Zelich is sentenced on March 30. Zelich was originally facing charges that carried up to life in prison without the possibility of parole, but Graveley said the former officer’s defense attorneys reached out to him Friday about a plea agreement.

Zelich’s attorney, Jonathan Smith, said his client decided he would rather plead guilty than go to trial. He declined to elaborate, but has long said that the death “was a non-intentional act.”

Zelich met Gamez online and invited her to Wisconsin, according to court records and testimony. He picked her up at the Milwaukee airport and they drove to a Kenosha hotel, where they spent several days. Zelich told investigators they played a sexual game in which he would choke Gamez. On the last day, he lost control and choked Gamez until she died, according to the criminal complaint.

Zelich told investigators that he put Gamez in her suitcase and took it to his West Allis apartment, and then stashed her body in his refrigerator.

Simonson, of Farmington, Minnesota, died in similar circumstances in November 2013. According to court documents, Zelich said he met her online and killed her while playing the same choking game at a hotel in Rochester, Minnesota.

He drove home to Wisconsin with her body and later put both bodies in suitcases in his car’s trunk. When they began to smell, he dumped them on the roadside, where highway workers mowing grass found them in June 2014, according to investigators.
