"He had a gunshot wound to the heart and an external wound to the back.", quoted from Inquirer's report.
The current issue on "pabon" system of the military seems to be too hot handle that one of its former officer would take his life. That's the saddest part of the on-going investigation.
Here's one of former officer have said,from ABS-CBN news site about their deeper investigation about the anomaly,
"top military officials seem to be lying in beds of cash, while ordinary soldiers like him would have to undergo long and tedious process of following up their retirement papers just to claim minimal benefits."
I just hope that even Angelo Reyes committed suicide or just got killed, the investigation would still push through and truth will be prevailed to the public.
