CEBU CITY-- The older brother of Lapu-Lapu City drug personalities, the Oyao brothers, was shot dead outside his sari-sari store on Saturday night.

Washington Oyao, 64, was shot at around 9 p.m. by unidentified gunmen. He was brought to the Mactan Doctor's Hospital but was declared dead on arrival.

Neighbors of Oyao said they heard two gunshots in the area.

According to the Lapu-Lapu City police, they are looking at the possibility of personal arguments as the cause of the shooting.

Investigation will also focus on possible drug-related activities since the victim is related to the Oyao brothers.

Last July, Rolando Oyao and his brothers, Paquibot and Donie, surrendered to the police in "Oplan Tokhang."

The three were identified as major drug dealers in Lapu-Lapu city.
