DNA Links and PM Prints Drive Hunt for Killers of Ex–São Paulo Police Chief Ruy Ferraz Fontes

Forensic analysis of a Praia Grande house uncovered dozens of genetic traces, prompting an internal probe into PM‑linked fingerprints.

Overview

  • Dahesly Oliveira Pires, 25, was arrested and, according to police, admitted transporting a rifle a day after the ambush that killed Ruy Ferraz Fontes.
  • The court ordered the detention of Luiz Antonio Rodrigues de Miranda, who investigators say directed the retrieval of a rifle and was seen with a black car used in the attack.
  • Genetic material found in cars tied Felipe Avelino da Silva, known as Mascherano, and Flávio Henrique Ferreira de Souza to the crime, and both remain fugitives.
  • Police forensics collected 41 genetic samples in a Praia Grande property linked to the group, and the PM’s internal affairs opened inquiries after finding fingerprints attributed to a military police officer and his brother.
  • Authorities say evidence points to organized crime involvement, with the PCC under scrutiny, while the motive remains under review and search operations continue for three principal suspects.
