HARRISONVILLE, MO. ? Serial killer John E. Robinson Sr., already sentenced to death in Kansas, was arraigned Tuesday in Missouri on charges of killing two women and a teenage girl.

Robinson, 59, sat silently through his first appearance in Cass County Circuit Court as Associate Circuit Judge William Collins entered “innocent” pleas for murder, fraud and forgery. Collins also scheduled a preliminary hearing May 14 for Robinson.

Prosecutors have the option of presenting the case to a grand jury instead of holding the preliminary hearing, Cass County Prosecutor Chris Koster said.

Robinson faces capital murder charges in Cass County for the deaths of Beverly Bonner, 49, of Cameron; Sheila Faith, 45; and her paraplegic daughter, Debbie, 16, both formerly of California. Their bodies were found on June 5, 2000, stuffed in barrels in a Raymore storage locker rented by Robinson.

He was sentenced to die in Kansas for the deaths of Suzette Trouten, 27, of Michigan, and Izabela Lewicka, 21, a former Purdue University student. Their bodies were found on his rural Linn County property. Robinson killed both women after luring them to engage in sadomasochistic sex.

Johnson County Judge John Anderson III also sentenced Robinson to life in prison for the 1985 death of Lisa Stasi, a 19-year-old whose body was never found.

Robinson might avoid the death penalty in Missouri if he leads law enforcement to Stasi’s body and the bodies of two other missing women who have been linked to him.

Stasi, Catherine Clampitt and Paula Godfrey disappeared in the 1980s. The women’s families and law enforcement officials want those cases resolved as well, Koster said.

“I want to try this case…,” Koster said. “But my desire to try it takes a back seat to important law enforcement goals.”
