A 16-year-old boy in General Santos City died while his mother is in critical condition, as of this writing, after the boy’s elder brother allegedly hit their head with a hammer.

The victims were brought to the hospital, but the boy was declared dead on arrival.

Police said the 30-year-old suspect allegedly hit his brother and mother while the victims were sleeping.

The suspect did not escape and was arrested after the incident. Authorities also recovered the hammer he allegedly used.

The suspect claimed he was possessed by Satan and said he could not remember anything he did.

“Murag kusgan kaning satanas ning kwan (misulod) sa akoa…wala ko kahinumdum…wala nakoy pamuot,” the suspect said.

Investigators said relatives have said the suspect is suffering from a mental condition.

“Based sa information natin sa mga kaanak ng suspek, may sakit sa utak… minsan lumalabas yung (pagka-wild) kasi may maintenance so baka hindi nila napansin, hindi nakainom ng maintenance,” Police Station 7-GSCPO Commander, Major Gaspar Maguiwe, said.

Police are awaiting the decision of other family members on the next steps to take with regard to the suspect but the suspect may be placed under rehabilitation.
