Olathe ? Questionnaires have been mailed to hundreds of prospective jurors in the serial murder trial of John E. Robinson Sr.

The goal of the more than 90 questions: Determine how much potential jurors know about the case and their attitudes about capital punishment.

Robinson is charged in Johnson County with killing three women: one who disappeared in 1985 and two whose bodies were found two years ago on his Linn County property.

He is also charged in Cass County, Mo., with the murders of two women and a girl whose bodies were found in a storage locker.
