Authorities in southwest Houston say a man may have been killed early Monday morning over his choice of karaoke songs.

Investigators told KPRC that the incident happened around 2 a.m. at Ostioneria Mazatlan, a Mexican seafood restaurant.

The victim reportedly yelled that he was from Guerrero, Mexico after singing “Somos Mas Americanos,” which means “We Are More American.”

"One of the gentleman, as soon as he stepped off the stage, someone didn't agree with the song or the music or something, and there was an altercation inside the restaurant," Houston Police Department's Sgt. J.J. Wilson explained.

One employee recalled that the two men had been shouting at each other across the restaurant.

"(The shooter) told him to shut up (and said) 'Why are you screaming the name of that town?'" the employee told KPRC. "(The victim) said, 'Why? It's my town.'"

One witness told KRIV that the two men were arguing about the choice of music when the singer was shot in the head.

"Some people showed up, and they didn't like what the other guy was singing ... so [someone] shot him," the witness said.

Wilson said that the shooter was seen leaving in a red Chevy pickup truck with "several other men." Two women, who were also with the shooter, later fled in a green Nissan Pathfinder.

Earlier this month in California, 70-year-old William Oller, Sr. was arrested for shooting his own son, 50-year-old William Jr., for singing a Kenny Chesney country tune.

In recent years, there has been so much violence related to the singing of Frank Sinatra songs at karaoke bars in the Philippines that the media began referring to the incidents as "My Way Killings."

"I used to like ‘My Way,’ but after all the trouble, I stopped singing it," one singer told The New York Times in 2010. "You can get killed."
