ILOCOS SUR – A 39-year-old funeral parlor owner was shot dead in Barangay Poblacion Norte in the town of Sta. Maria on Wednesday.

Miguel Dizon II was jogging with his wife Reyna when they were approached by two unidentified assailants wearing bonnets.

The suspects shot the victim several times, but left his wife unharmed.

Dizon was rushed to Ilocos Sur District Hospital-Narvacan, but was declared dead on arrival.

Responders to the scene recovered four empty shells from an M16 Armalite rifle.

According to the police, Dizon was on their drug watch list, categorized as a suspected drug user.

He reportedly surrendered to the authorities last month as part of anti-drug operation Oplan Tokhang.

"Pinag-aaralan natin lahat ng possible motives pero sa ngayon wala pa talaga tayong masabi kung bakit siya pinatay," said Sta. Maria, Ilocos Sur Chief Inspector Anthony Otinguey.

Dizon's family declined to comment
