MILWAUKEE (AP) -- A state-hired psychiatrist has decided that an Iraq War veteran was not suffering from a mental disease when he allegedly killed his wife while she was on duty as a suburban Milwaukee police officer. The report was discussed during a hearing Friday in the case of Benjamin Sebena (se-BEE'-nah). Prosecutors say Sebena admitted to fatally shooting his wife Jennifer Sebena in Wauwatosa (wah-wah-TOH'-sah) on Christmas Eve. He has pleaded not guilty by reason of mental disease or defect. His attorney has also hired a doctor to examine him and that report is expected to be reviewed at a June 21 hearing. A judge is also expected to issue a ruling then about whether Sebena's alleged confession to police should be thrown out. His trial is set for July 8.
