(CBS/AP) KANSAS CITY, Mo. - Harry Irwin, a 93-year-old Kansas City man, is charged with killing his 95-year-old wife, Grace Irwin, in what investigators are calling a homicide and attempted suicide.
"Yes, I killed her and then killed myself. Why am I awake?" Harry Irwin allegedly told a Kansas City Fire Department paramedic who was transporting him to the hospital, CBS affiliate KCTV reports.
The Jackson County prosecutor filed the second-degree murder charge Wednesday against Harry Irwin, who remained hospitalized, in serious but stable condition, with self-inflicted stab wounds to his chest.
The couple's daughter said her father called her at 6:30a.m. Wednesday and told her to come to the house at 9a.m. She told police that her father indicated that her mother was dead, the station reports.
When the daughter arrived at the scene, she found her mother lying in a blood-filled bed, according to court documents obtained by KCTV.
The daughter said her unconscious father was sitting in a char with a knife in his hand. Her brother also rushed to the scene and found a suicide note, the court documents say.
Paramedics who responded to the scene confirmed they found blood on Grace Irwin's head but would not say how she died.
Harry Irwin reportedly claimed his wife had been "arguing and screaming at him all night and he couldn't take it anymore," according to court documents.
KCTV reports he said he couldn't remember what he hit his wife with but he just knew he "did her in."
