Why any American would go to Tijuana for a weekend of partying in the midst of the largest outbreak of drug cartel violence on record is beyond me:

The bodies of four U.S. citizens were found strangled, beaten and stabbed in a van in this border city, two days after they reportedly left their Southern California homes for a night at the Mexican clubs, U.S. officials said Thursday.

The victims, ages 19 to 23 years old, were found tied up on Saturday, but their deaths were not reported earlier because they were under investigation, said Fermin Gomez, an assistant state prosecutor in Baja California.

I’ve always had a hard and fast rule against vacationing in Third World countries. It’s harder and faster now. (Pre-emptive comment: Some scholars say Mexico is no longer Third World, but is now a “developing country.” I’m not going to quibble about it. Call it what you like and I’ll do the same.)
