Police in Brazil are searching for the killers of the former head of a Sao Paulo death squad who was shot a month after being released from a lengthy jail term.
Florisvaldo de Oliveira, an ex-policeman known as Corporal Bruno, had served nearly 30 years for murdering at least 50 people.
He was shot dead in an ambush as he drove his family home from church.
