Olathe ? A six-page sex slave contract between John E. Robinson Sr. and Izabela Lewicka was among dozens of documents police seized from Robinson’s home and storage locker, detectives testified Friday.

Labeled “basic slave rules,” the contract listed 115 rules Lewicka would have to follow for her master, Robinson. Prosecutors in Johnson County District Court used the documents as more evidence linking Robinson to Lewicka’s death and a sadomasochistic lifestyle.

Robinson, 58, Olathe, is charged with capital murder in the deaths of Suzette Trouten, 27, Newport, Mich., and Lewicka, 21, a former Purdue University student. Their bodies were found in barrels on Robinson’s rural property in Linn County.

Robinson also is charged with first-degree murder for the death of Lisa Stasi, who disappeared in 1985 and whose body has not been found. Robinson also awaits trial on three murder charges in Missouri.

Lenexa Police Detective Dan Owsley identified dozens of documents taken from Robinson’s home at Santa Barbara Estates Mobile Home Park and from a storage locker in Olathe.

The documents provided links to Robinson and the victims, including the three found in Missouri.

Among the items found in the storage locker were a black case with items linked to Lewicka and a brown briefcase with items linked to Trouten, including driver’s licenses, Social Security cards and high school diplomas for each victim.

Detectives also found 1998 and 1999 Social Security benefit statements for Sheila and Debbie Faith, the mother and daughter whose bodies were found in barrels in a Raymore, Mo., storage locker. Also found was a photocopy of two U.S. Treasury checks to the Faiths in the amount of $582 each dated Sept. 3, 1997.

An Internal Revenue Service application for an employee identification number was found for Beverly Bonner, the third victim found in the Raymore storage locker.

A common thread of the documents were the multiple addresses and e-mails for Robinson’s business and personal use. Copies of those e-mails sent to Trouten and other women seeking sexual relations were admitted into evidence Friday.

Among those e-mail addresses were “midwestmaster” and “eruditemaster.”

The testimony Friday concluded the first week of the trial, which is expected to last four to six weeks.
