Zayda Peña Arjona was the lead singer for the popular grupero band Zayda y Los Culpables. The band's popularity reached its peak with the song "Tiro de Gracia (Coup de Grâce)" about a woman's failed relationship.
On Nov. 29, 2007, Peña was staying at the Monaco Motel in Matamoros, Tamaulipas, just near the U.S.-Mexico Border. An unknown gunman opened fire on Peña, her friend, and a motel employee. Although Peña was shot in the back, she survived the attack. Her friend and the motel employee both died at the scene.
Peña was taken to a medical facility, where doctors determined the bullet wound was not life-threatening. While resting in the medical facility, after a successful operation to extract the bullet from her back, two gunmen entered the hospital, found her, and shot her point blank in the chest and face. She died instantly.
Although Peña never made a song about drug traffickers, her mother worked at a public prosecutor's office.
