PO1 Jonathan Morales, officer-on-case, identified the victim as Randolph Strickland, of Barangay Sto. Rosario, Pateros.
Morales said the victim tried to persuade a store owner at around 3:15 a.m. to give him several bottles of beer which he promised to pay later.
The store owner, Cecilia Solidum, reportedly refused and a heated argument ensued.
The victim went home and brought with him a caliber .38 revolver and a hand grenade, which he used to threaten Solidum.
A bystander, however, tried to pacify the two. When Strickland went home, his neighbors said they heard a loud explosion.
Police probers said Strickland, who was drunk, could have accidentally pulled the grenade’s pin and it exploded, killing him instantly.
