Cristobal Perez was born on August 14, 1969 in San Antonio, Texas to Gilbert Perez, a computer programmer, and Carmen Medina. He is of Mexican-American ancestry. Perez's parents divorced in 1974, when he was four years old. His mother remarried in 1978.

In spring 1995 Chris's father-in-law, Abraham found out Yolanda Saldivar, who managed Selena's boutiques and fan club, was embezzling money. They held a meeting in early March where it was rumored they had a sexual relationship, with Saldivar denying she had anything to do with fiscal discrepancies in checks that were found written in her name. Selena tried to repair her friendship with Saldivar despite her father's warnings. On March 30, 1995, Selena and Chris met with Saldivar at a motel to recover missing financial papers for tax purposes. When Selena arrived home she found that Saldivar did not give her the correct documents. She phoned Saldivar, who tried to convince Selena to return to her motel room alone. Chris insisted that it was too late, and he did not want Selena driving alone at night. Selena then agreed to meet with Saldivar the next morning.  On March 31, Selena woke up early to meet Saldivar at the motel where she was staying. She met with Saldivar, who delayed the transfer of papers with a story about having been raped in Mexico. Selena took Saldivar to a local hospital, where doctors found no evidence of rape. When they returned to the motel room, Selena ended their four-year working relationship. As she turned to leave, Saldivar reached into her handbag, pulled out a Taurus Model 85 .38 caliber revolver, pointed it at Selena and pulled the trigger. The bullet entered Selena's right shoulder blade from the back, piercing a major artery running from her heart and exiting from just below her right collarbone. She ran to the motel lobby and collapsed to the floor. As the motel employees gathered round, she named Saldivar as her assailant. Selena was transferred to a nearby hospital, where doctors found the damage irreparable. She was pronounced dead within the hour.  Chris couldn't eat for two days after his wife's murder. In his book he says that when he could not sleep he began abusing alcohol and other drugs, and went into seclusion. Family members noticed he was rapidly losing weight. Chris felt guilty for not protecting Selena from Saldivar.  In 1996, he moved out of his Corpus Christi house and back in with his father in San Antonio. John Garza introduced him to Venessa Villanueva, and after getting to know each other they became a couple in 1998. In 2001 Chris married Villanueva and they had two children, a boy and a girl.  Although it was rumored that Villanueva did not want to divorce, and wanted to try and work things out in their relationship, the couple finally decided their relationship was irreconcilable. They filed for divorce in 2008. Despite getting married again and having two children, Perez has since remained in touch with the Quintanillas following Selena's death.
