Police said Araújo, reported by local media to be a laboratory technician, used a 9 mm pistol and carried two additional clips, extra ammunition, a knife and unspecified but unused explosives.
Investigators are analyzing the explosives in addition to a cell phone and audio recorder found in a car he parked outside the home to determine whether Araújo left any sort of message about his
attack.
Police said they did not yet know if Araújo had a history of violence, or whether he had been known to physically harm or threaten his former wife before the attack. Campinas, an industrial and university city of over 1 million residents, is located about 100 kilometers (60 miles) northwest of the city of São Paulo, Brazil’s biggest metropolis.
