HARRISONVILLE, MO. ? Cass County officials have declined comment on a hearing scheduled today for serial killer John E. Robinson Sr.

Robinson, already convicted of capital murder and facing a death sentence in Kansas, faces three counts of first-degree murder and three counts of armed criminal action in Cass County. In May, he entered innocent pleas to those charges.

Cass County Prosecutor Chris Koster decline to reveal the purpose of today’s hearing and said he could not comment on any possible plea negotiations with Robinson.

Koster has previously said he would be willing to drop his pursuit of a death sentence on three pending murder charges if Robinson would lead investigators to the bodies of three women who have been missing since the 1980s.

The missing women are Paula Godfrey, 45, who disappeared in 1984 at the age of 19; Lisa Stasi, also 19, who had a 4-month-old daughter when she disappeared in 1985; and Catherine Clampitt, who was 27 when last seen by her family in 1987.

In Missouri, Robinson is accused of killing Beverly Bonner, 49, of Cameron; Sheila Faith, 45, and her paraplegic daughter, Debbie, 16, both formerly of southern California. Their bodies were found on June 5, 2000, stuffed in barrels in a Raymore storage locker rented by Robinson.

Trial was scheduled to begin in March 2004 with a jury selected from across the state in Franklin County.

In Kansas, Robinson was sentenced in January to die for the murders of Suzette Trouten, 27, of Michigan, and Izabela Lewicka, 21, a former Purdue University student. Their bodies were found on his rural Linn County, Kan., property.

Robinson also was sentenced to life in prison for the death of Stasi.
