Monday is the second anniversary of the disappearance of 43 students in the Mexican state of Guerrero.
They're known as the Ayotzinapa 43. The name comes from the town of Ayotzinapa, which is where they all attended a teacher training college.
A government investigation concluded that the students were detained by corrupt local police officers. The police reportedly turned the 43 over to a drug cartel's gang members, who then allegedly executed the students.
But two years later there's still no conclusive evidence. The fate of the students still remains a mystery.
And the investigation has long been stalled. Many accuse Mexico's federal government of complicity in the case.
Los Angeles-based musician Gabriel Garcia doesn't want people to forget the Ayotzinapa 43.
Garcia fronts the band Changui Majadero and on the group's debut album, they perform a tune dedicated to the missing students.
The song is called "Changui Pa' Ayotzinapa," and it was written by Gabriel's dad, Felix Garcia.
"My father writes Mexican corridos [songs], but with a political twist," Gabriel Garcia says.
Both of Garcia's parents are from Mexico, while he was born in LA.
And Gabriel Garcia says the song is more than just a remembrance for the missing 43 students. It's also dedicated to all other victims in Mexico — where a long-running drug war and other violence have led to thousands of deaths and unsolved missing cases in many parts of the country.
Garcia says, "It also talks about other massacres that happened in Mexico and how Ayotzinapa isn't the only situation. It's a recurring situation where the Mexican government is very oppressive towards its people, towards students, teachers. And how the narcos, the drug dealers and the government is one and the same. They're partners and this is affecting the violence."
