13-Year-old Boy Shoots His Parents To Death & Grandmother Before Killing Himself

A 13-year-old boy killed his police officer parents as well as his grandmother and great-aunt before spending a full day at school and then taking his own life.
Police believe Marcelo Pesseghini shot each victim in the head with a .40 caliber pistol early Monday morning at the home in Sao Paulo, Brazil, before catching a lift into school with a friend.
The father, Luiz Pesseghini, 40, a police sergeant with 19 years service was found in bed. The mother, Andreia Pesseghini, 30, who had served in the military police for 16 years was found on her knees in the bedroom.
The teenager was found dead from a gunshot to the left temple and his father’s police-issue service revolver was found nearby.
A second gun, a .32 caliber revolver, was found inside the backpack the teenager took to school.

CCTV footage taken from a security camera close to the property in the Brasilândia district in the northern part of São Paulo appears to show him casually walking back home after school.
Everything seems to indicate that Marcelo (Pesseghini) killed his parents and relatives,’ Itagiba Franco, of the Sao Paulo Civilian Police’s homicide department, told a press conference.
Franco said Pesseghini had told a friend he wanted to kill his parents and become a hitman.
‘He always told me he wanted to become a hired killer. He had a plan to kill his parents during the night, so that no one would notice and escape in the parents’ car and live in an abandoned place,’ police quoted the unidentified friend as saying.
