Adam Sapikowski agreed to plead guilty last week to two counts of second-degree murder for killing his parents in 2005.
Sapikowski, 19, was set to go on trial for murdering his parents, James and Alison Sapikowski, but instead will plead guilty for the murder of his father on Friday and for the murder of his mother next week. He will serve between 40 and 50 years in prison.
