In a news briefing Monday morning, retired policeman Arturo Lascanas backed up 2016 allegations made by former hitman Edgar Matobato, including claims of a 300-member execution squad run out of the southern city of Davao.
"I was one of those who started it," he said. "We implemented the personal instructions of (then-Mayor) Duterte to us. All of the killings we did in Davao city, whether we buried or threw them out to sea."
