The woman was OK and treated at the scene, police said. After the shooting, the man told police that Conrad Perez, 17, mentioned the incident to him, saying he and his friends were the ones responsible, according to an arrest affidavit. Perez, who was already in custody on an unrelated charge of unauthorized use of a motor vehicle, later shared details about the shooting with detectives, the affidavit said. Perez said his friend, Todd Smith, 17, wanted to rob the man and he had agreed to participate in the robbery, the affidavit said. According to the affidavit, Perez was outside the apartment in a stolen 2009 Toyota Camry acting as the getaway driver, and Jonathan Cruz Garcia, Smith and the 15-year-old boy were the shooters. On Jan. 25, four days after the shooting, police said officers took Perez and the teen boy into custody after they were spotted in the stolen Camry.
