Jurors at Aaron Schaffhausen's insanity trial have viewed graphic photos of the Wisconsin crime scene where Schaffhausen has admitted killing his three daughters.
Forensic image specialist Larry Ventura testified for the prosecution Friday. Ventura showed images of the girls' bodies, their bedrooms and pools of blood on the carpet.
KSTP-TV reports Schaffhausen didn't look at any of the photos.
Anna Sorenson with the Wisconsin State Crime Lab testified about the murder scene she saw and the condition of the girls. Police found the girls -- 11-year-old Amara, 8-year-old Sophie and 5-year-old Cecilia -- dead in their beds in their River Falls home.
The prosecution contends Schaffhausen killed his daughters to get revenge on his ex-wife. The defense maintains Schaffhausen was legally insane at the time of the July killings.
