(Reuters) -- "We have finally established the identity of the perpetrator," Oscar Albayalde, chief of the capital's police office, told a media briefing on Sunday. "He is heavily indebted due to being hooked on casino gambling, according to his immediate family," Albayalde said, reiterating the attack was not a terrorist act.

The casino's CCTV showed the gunman firing shots at the ceiling and setting gaming tables ablaze. At least 36 people died.
