A jury is officially seated in the Aaron Schaffhausen case. The jury includes nine women and six men. At this point, it's unclear which jurors are the three alternates.
Schaffhausen originally pleaded not guilty by reason of mental disease or defect in last summer's slayings of his daughters in a River Falls, Wis. home.
On Thursday, he changed his plea to guilty while maintaining an insanity claim.
Schaffhausen arrived at court Monday morning wearing slacks, a shirt and a tie.
The selection process of the jury included 105 potential jurors.
During the selection process some of the potential jurors answered that they could not be fair and impartial during the trial, considering the crimes Schaffhausen has admitted to.
Schaffhausen, a construction worker from Minot, N.D., faces three counts of first-degree intentional homicide.
His daughters, 11-year-old Amara, 8-year-old Sophie and 5-year-old Cecilia, were found dead in their beds July 10. The girls lived with Schaffhausen's ex-wife Jessica.
According to authorities, their throats had been slit, and gasoline had been poured in the basement in an apparent attempt to burn the house down.
Opening statements in the case will begin at 8:30 a.m. Tuesday. The defense will begin to present its case and Schaffhausen's public defender says the first witness he plans to call will be the first officer who interviewed Schaffhausen on the day of the murders.
