Friends and family members searching for answers were forced to listen to how their loved ones, Chip Northup and Claudia Maupin, died.

In Friday’s preliminary hearing, investigators say 16-year-old Daniel Marsh admitted to stabbing the couple to death.

“He stated that he wore a black mask and black pilot’s jacket.” said one investigator, going on to say Marsh admitted to breaking into the couple’s home through a window, watching the couple sleep, then attacking the couple in bed.

According to other testimony, both were stabbed more than 60 times each. Claudia begged him to stop as she died. Prosecutors say Marsh confessed to then mutilating their bodies.

And it doesn’t stop there. Investigators told the court Marsh conceded he had plans to kill again.
