I will not make that assumption. BUT it would not surprise me. PCB is NUTS on SB! It is ranked as the 2nd most popular SB destination in the world, behind Cancun. I went there for my high school senior year SB and again my freshmen year of college ('02 and '03 spring breaks), and I have never seen anything like it. They have tons of resorts where the balconies are a popular party spot, and it gets loud and crazy 24-7 the whole time you are there.
Again, I am not saying he was partying, or drunk. Definitely a sad story though.
