Jurors in the Aaron Schaffhausen insanity trial were shown graphic crime scene photos Friday that were taken inside the home where the River Falls, Wis., man murdered his three daughters last year, KARE 11 reports.
Shaffhausen, 35, pleaded guilty to murdering the girls last month. Jurors in St. Croix County will decide whether he was sane or not at the time of the killings.
The Pioneer Press says Schaffhausen's eyes were cast down as the photographs were shown and did not appear to the react. Family members of the girls, however, became emotional.
The photos -- some of which showed a large amount of blood -- were displayed by prosecutors as two state crime lab employees took the stand, the Pioneer Press reports. Some 600 photos were reportedly taken at the crime scene.
According to KARE, some of the images were of the girls' bedrooms, and others showed blood stains on the carpet, staircase, and in the washing machine.
The defense rested its case on Wednesday, and Schaffhausen did not testify.
The defense is arguing that Shaffhausen was insane when he murdered the girls -- Amara, 11, Sophie, 8, and Cecilia, 5 -- last July; but prosecutors argue that he was sane and committed the acts to hurt his ex-wife and mother of the girls.
Prosecutors are still expected to call a mental health expert to testify.
The Hudson Star Observer reports that the jury is expect to get the case Tuesday.
If found to be insane, Schaffhausen will be committed to a mental health institute, possibly for life, the Pioneer Press reports. If he is found to be sane, he will be sentenced to life in prison.
