The Confession and Crime Details

• 💡 13-year-old honor student Derek Rosa confessed to murdering his mother while she was sleeping, next to her two-week-old infant daughter.
• 📞 Rosa called 911 himself after the incident, stating he had killed his mother and describing the bloody scene.
• 🔪 He admitted to stabbing her 48 times with a 7-inch knife, specifically targeting the carotid artery, which he had researched online.

Premeditation and Aftermath

• 🔍 Prior to the murder, Rosa conducted Google searches on topics like "best place to stab someone," "is a small knife good for killing," and "can a knife cut through bone," also requesting a diagram of the carotid artery.
• 📸 Immediately after the killing, he took bloody selfies and sent them to online friends, appearing to be excited and even sticking out his tongue.
• 🗣️ During his police interview, Rosa was stoic and methodical, only asking for a lawyer when directly questioned about his motive ("why").

Legal and Psychological Analysis

• ⚖️ Legal experts highlighted the need to scrutinize if Rosa, as a juvenile, was properly Mirandized and if his confession was truly voluntary, given his age.
• 🧠 Psychologists noted his disassociated state and lack of emotional response, suggesting a detachment from the gravity of his actions, though not necessarily legal insanity.
• ⚠️ The defense's attempts to seal the confession and move Rosa to a juvenile facility were rejected by the judge.

Court Proceedings and Future

• 👨‍⚖️ Rosa is currently being held in an adult jail, segregated from the general population, and is set to be tried as an adult.
• 🙏 His father, Jose Rosa, has publicly asked for leniency and a second chance for his son.
• 📅 The trial is anticipated to begin in March, with the defense continuing efforts to prevent him from being tried as an adult.
