After some speculation Tuesday, Aaron Schaffhausen decided not to take the stand in his insanity trial, WCCO reports.
The defense rested their case Wednesday morning.
Schaffhausen's attorneys called their final witness, San Diego psychologist J. Reid Meloy, Tuesday.
Meloy testified that Schaffhausen was legally insane when he killed his three daughters, 11-year-old Amara, 8-year-old Sophie and 5-year-old Cecilia, in River Falls last summer.
The psychologist spent 10 1/2 hours interviewing Schaffhausen over two sessions and determined his history of depression combined with a personality disorder made him not legally responsible for the murders.
On Monday, a court-appointed medical expert said otherwise, testifying that Schaffhausen suffers from major depression, but was not insane.
The prosecution called their first witness, Schaffhausen's neighbor, Wednesday morning.
Schaffhausen, 35, pleaded guilty to killing the murders of his three children. Now, it's up to a jury to decide if he was sane at the time.
