POLICE arrested on Tuesday night the principal suspect in the killing of an elderly woman and her 14-year-old granddaughter in Plaridel, Bulacan.
Suspect Jay Vincent Mamerto, 27, turned out to be a neighbor of victims Silvia Castillo, 63, and her granddaughter Cyreen Margarette San Pedro in Isabel Village in Bgy. Tabang, Plaridel municipality.
A 7-year-old brother of San Pedro managed to escape at the height of the suspect’s rampage inside the Castillo-Molina house around 5:51 a.m. last Monday.
The boy is recuperating from his wounds in a local hospital, said Police Regional Office 3 director Chief Supt. Joel Napoleon Coronel.
An investigation showed Mamerto managed to enter the victims’ house unnoticed. The suspect attacked the victims with a knife after the old woman and her teenager granddaughter discovered his presence inside their house.
Castillo was stabbed twice in the body while her granddaughter suffered 10 knife wounds. Both were pronounced dead upon arrival in a local hospital.
The teenager’s brother was stabbed 12 times.
The suspect, an employee of a local pet shop, was seen in CCTV footage hurriedly leaving the scene of the crime. He was found to have scratches on his shoulders, indications that the victims tried to fight him back.
Officers led by Supt. Arwin Mateo solved the crime with the help of a witness.
The Plaridel police said they recovered a blood-stained pants worn by the suspect during the attack.
During questioning, the suspect claimed he tried to steal from the victims’ house for the medical expenses of his wife who is soon to give birth. Mamerto said he had no intention to kill the victims.
The suspect apologized to the victims’ families although his apology was not accepted. The Castillo-Molina families said they could have easily given the suspect some money had he asked for it.
The Plaridel municipal government earlier offered a P100,000 reward for any information that would lead to the immediate solution of the case.
