Steven Zelich is charged with first degree intentional homicide in the death of Jenny Gamez.
Zelich says they met online and she flew to Wisconsin in 2012. He says they spent several days in a hotel, engaging in sex, bondage and a choking game that went too far.
Zelich is also a suspect in the death of a Minnesota woman, under similar circumstances.
The bodies of both women were found in suitcases on a rural highway in Wisconsin.
