A shocked courtroom heard Derek Rosa tell police he stabbed his mother to death in her sleep as his baby sister slept next to her in the bed.

After hearing the teen's taped confession, Miami Dade Circuit Judge Richard Hersch rejected a defense motion to move Rosa out of the adult jail and into a juvenile facility. The defense says it is unconstitutional to keep Rosa in an adult cell, claiming he is being kept in unsustainable conditions and is only allowed outside the cell for 20 hours a week.

After rejecting the motion, the judge orders Rosa to be held in the Miami-Dade Metro West Detention Center until his unscheduled trial begins.

Reportedly, the night Derek Rosa stabs his mother to death, he makes six Google searches including,

“What is the best place to stab someone?” "
"Is a small knife good for killing?” “
"Is it easier to kill someone with a small knife?”
“Can a knife cut through bone?”

He also searched for an image of The Carotid Artery diagram. The DailyMail reports the last search made that night was to inquire about a machine gun.

Derek Rosa claims in a police interview that his stepfather owns two guns and he planned to shoot himself after the stabbing but didn't go through with it.
