From the front page of The Manila Chronicle, here's the full news account of that fateful day---
Arturo Porcuna, alias "Boy Golden," notorious police character and two of his henchmen were gunned down by members of a rival gang in the room of an apartment in Mandaluyong, Rizal shortly after 2 o'clock this morning. Killed with Porcuna were two new members of his gang known as "Jojo" and Bert". Their real names were not immediately available as they reportedly joined Porcuna's gang only a few days ago.
The wife of Porcuna known as Marla and Anita Dee, the wife of San Miguel, were in the other room when the shooting took place. With them in their room was their housemaid.
When the police arrived, they found the bodies of Porcua, Jojo and Bert all riddled with bullets. They found on the flo0r empty shells of an automatic carbine and a Thompson submachinegun. The police were inclined to believe that the victims were surprised in the room by the gunmen who were obviously on a mission to liquidate Porcuna and his henchmen.

I never had a chance to see this movie when it made its theatrical run in 1978. It earned money and made a noise when it won the Gawad Urian's Best Actress for its lead star Beth Bautista. I think it never came out in video format and I am wondering if a copy still exists.
"Hindi Sa Iyo ang Mundo, Baby Porcuna" (1978)- Stars Beth Bautista, Joseph Sytangco, Dick Israel, Anthony Alonzo, Josephine Garcia, Suzanne Gonzales/ Directed by Danny Zialcita
Halaw sa tunay na pangyayari, isinasaad ng Hindi sa Iyo ang Mundo, Baby Porcuna ang buhay ng kapatid na babae ni Boy Golden, isang kilalang maton noong 1960's. Si Baby Porcuna (Elizabeth Bautista) ay isang mananayaw ng burlesk sa tanghalang pinamamahalaan ni Cris (Dick Israel).. Nahahalayan sa hanapbuhay ng kanyang kapatid, kinuha ni Boy (Anthony Alonzo) si Baby habang nagsasayaw sa tanghalan, at iniuwi sa apartment na kanyang tinutuluyan upang ilayo kay Cris kahit may anak na si Baby rito. Nakilala ni Baby si Tommy (Joseph Sytangco), isang mang-aawit sa tanghalan ni Cris. Nanligaw si Tommy at nag-alok ng kasal. Matapos matuklasan ni Baby ang pakikipag-ulayaw ni Cris sa ibang babae, nabuo ang kanyang pasyang iwanan ito at magpakasal kay Tommy. Naging maunos ang kanilang pagsasama dahil sa kaugnayan ni Baby kay Boy Golden at sa magulong pamumuhay nito. Ang pakikipag-alitan ni Boy dahil sa dalawang babae, kina Emma (Josephine Garcia) at Susan (Suzanne Gonzales) ang naging sanhi ng kanyang kamatayan. Natanto naman ni Cris na tunay na may pagtingin siya kay Baby. Binayaran niya si Tommy upang layuan si Baby. Nasaktan si Baby at bilang ganti ay sinabuyan niya ng asido si Tommy. Nagsisi si Baby nang malamang si Cris ang may kagagawan ng lahat, ngunit tulad ng ugnayan nina Boy, Emma, at Susan, ang kina Baby, Cris, at Tommy ay humantong din sa isang malagim na wakas.
