The police said Nicanor Librella, 44, a building inspector at the UP campus, sustained fatal head and body injuries and was pronounced dead on arrival at the universitys infirmary.
Police sources said Librella was an avid fan of Yan and that the actors death left him very depressed. Probers said Librella must have decided to kill himself when he found out that non-family members of the actor will not be allowed to attend the funeral.
Initial reports showed that the incident occurred at about 5:25 p.m. at the top of the National Engineering Center at the UP Campus in Diliman, Quezon City.
Investigators said Librella, who was on leave from work, was so distraught over Yans death that he went up to the fourth floor of the building allegedly with the intention to commit suicide.
There were some janitors present at the time, but they dismissed Librellas stunt as an "April Fools Day" joke, the police said.
Without warning, Librella jumped from the fourth floor and landed on the pavement. The shocked janitors rushed him to the hospital where he died at about 5:35 p.m.
