Michael Ray Canete, Calbiga police chief said Balledo and his friends were on their way home after attending a benefit dance at Barangay 5 in Calbiga town when he was shot twice at close range by Ocasla who was armed with a caliber .45 pistol.
According to police, Ocasla, who appeared to be drunk, did not resist arrest.
Ocasla is now detained at the Calbiga police headquarters as charges are being readied against him.
Karapatan said Ocasla
was a farmer arrested in 2007 and was one of those charged with multiple murder.
He said the case of Ocasla makes the release of political detainees not just 'a matter of justice, but also a matter of life and death.'
Ocasla's daughter said her family received assurances that her ailing father would be freed in time for Christmas.
In Davao City, the head of the government peace panel, Labor Secretary Silvestre Bello III, expressed sympathy for Ocasla's family and said more political prisoners would be released in the coming days.
'Bernabe Ocasla, who was detained on trumped-up multiple murder charges for nine years, was on a list of 130 ailing and elderly political prisoners provided by human rights groups to the peace panel of the Government of the Republic of the Philippines (GRP) after the latter said that it would prioritize them for release,' NDF panel said, adding that the list was later reduced to 70 names.
The group pointed out that government peace panel chief Silvestre Bello sympathized with Ocasla's family but also announced that the list will be further reduced to 50 names as the Duterte moves its self-imposed deadline for the releases from the month of November to December 10.
The government peace panel on Thursday sympathized with the family of detained peasant leader Bernabe Ocasla who died of an illness on Monday, and assured the National Democratic Front of the Philippines that the administration was already working to free other political prisoners.
The 66-year-old Ocasla was one of the political prisoners being considered for release on humanitarian grounds, but he suffered a heart attack before he could gain his freedom.
Arrested suspects were Andrew Abaigar Ocasla
from Argao town and Tomas Manulat Bracero of Sogod town.
