Daniel Green, a schizophrenic Oklahoma City man, is accused of killing four family members in August. Green told police he doesn’t remember because he blacked out, but said he might have “emptied a magazine on them,” according to the arrest affidavit filed in Oklahoma County District Court. This type of homicide case is rare, Oklahoma City Police Chief Bill Citty said. Of the 62 homicides reported in the city from January through September this year, mental illness was an obvious factor in “very few,” Citty said. “We track our mental health contacts, and most of our mental health contacts are nonviolent and end up going to the crisis center or the hospital to be evaluated,” the chief said. Although they are rare, cases like Green’s raise questions about the severely mentally ill, their easy access to guns and whether they are getting the help they need. Green’s father, Raymond Green, told investigators deep down he thought his son was capable of killing his family, a court document reveals. But Laquanna Cizek — who lost her mother, grandmother and two siblings that day — said she never saw her uncle do anything violent, despite his lifelong struggles with schizophrenia. “Something had to have pushed him,” she said.
