MANILA, Philippines—A 16-year-old boy was found lifeless with a nylon cord tied to his neck and mouth in Las Pinas City the other day.

Fatality Arman Solatre of Margie Moran Street, Riverside Dulo, Barangay Talon 2, was discovered by neighbors around 2:30 p.m. Wednesday hanging at the side of a creek near his home.

Police Officer 3 Ariel Gupana of the Las Piñas police said the teen was last seen watching TV around 1 p.m. before he disappeared.

The victim's mother claimed her son suffered from a mental illness and was taking medication for it.

The case investigator said he was ruling out foul play because no other physical injuries were found on Solatre's body besides ligature marks.
