Boyfriend Arrested After Forensics Find Polytrauma in Law Student’s Fall

Overview

• On September 13, 22‑year‑old law student Isabelle Caracristi was found dead after a fall from her building’s rooftop and a Pefoce necropsy identified polytrauma consistent with impact against the ground while toxicology and pregnancy tests were negative.
• The Tribunal issued a preventive‑detention order and the Polícia Civil arrested João Munhoz Neto on Tuesday, September 22, citing allegations that include inducing or instigating suicide (Article 122) and threats (Article 147).
• Investigators have seized the victim’s phone, the boyfriend’s phone, and a phone and tablet belonging to his mother and are forensically analyzing more than 700 video files and additional laudos that remain in progress under judicial secrecy.
• Security camera footage places Isabelle alone entering an elevator toward the rooftop at about 19:12 and records the fall near 20:40, while João left the building earlier and returned at about 22:48, and police are examining the timeline alongside reports that the apartment was cleaned and put up for sale the next day.
• Family members and witnesses describe controlling, jealous behavior by the boyfriend and cite messages in which Isabelle warned relatives not to trust him; the ongoing device forensics and remaining expert reports will shape whether prosecutors press charges beyond the preventive detention.
