Murder

The Quintanilla family appointed Yolanda Saldívar as manager of Selena's boutiques in early 1994. Eight months later, Selena signed Saldívar as her registered agent in San Antonio, Texas. After the agreement, Saldívar moved from San Antonio to Corpus Christi to be closer to Selena. In December 1994, the boutiques began to suffer after the number of staff for both stores had decreased. According to staff members, Saldívar often dismissed employees she disliked. Employees at the stores regularly complained about Saldívar's behavior to Selena, who dismissed the claims, believing Saldívar would not negatively impose erratic decisions on Selena's fashion venture.

According to Quintanilla Jr., the staff later turned their attention to him and began informing him about Saldívar's behavior. Quintanilla Jr. took the claims seriously; he told Selena to "be careful" and said Saldívar might not be a good influence. Selena dismissed her father's inquiries because he had often distrusted people in the past. By January 1995, Selena's fashion designer Martin Gomez, her cousin Debra Ramirez, and clients had expressed their concerns over Saldívar's behavior and management skills. During an interview with Saldívar in 1995, reporters from The Dallas Morning News said her devotion to Selena bordered on obsession.

According to Quintanilla Jr., in January 1995, he began receiving telephone calls from fans who said they had paid for membership in the Selena fan club and had received nothing in return for it, and he began an investigation. Quintanilla Jr. discovered that Saldívar had embezzled more than $30,000 via forged checks from both the fan club and the boutiques. Quintanilla Jr. held a meeting with Selena and Suzette on the night of March 9 at Q-Productions to confront Saldívar. Quintanilla Jr. presented Saldívar with the inconsistencies about the disappeared funds. Quintanilla Jr. told her that if she did not provide evidence that disproved his accusations, he would involve the local police. Quintanilla Jr. banned Saldívar from having any contact with Selena. However, Selena did not want to dissolve their friendship; she thought Saldívar was essential to the success of the clothing line in Mexico. Selena also wanted to keep her close because she had bank records, statements, and financial records necessary for tax preparation.

In the days before Selena's death, Saldívar delayed handing over the bank statements and financial records by saying she had been physically and sexually assaulted in Mexico. Saldívar, along with Selena, appeared at a medical clinic on March 31, 1995, ostensibly to have Saldívar examined for an assault which she claimed happened to her in Monterrey. During that visit, Saldívar was given a brief physical examination by the clinic's doctor, but this did not include a gynecological exam specifically done in cases of sexual assault. It was suggested by nurse Carla Anthony that Saldívar needed to have the rape exam in San Antonio for three reasons: Saldívar was a resident of San Antonio, the clinic they were currently at was in Corpus Christi, and the assault occurred in Mexico.

Afterward, Selena again met with Saldívar in her motel room at the Days Inn in Corpus Christi. At the motel, Selena demanded the financial papers. At 11:48 a.m. (CST), Saldívar got a gun from her purse and pointed it at Selena. As Selena attempted to flee, Saldívar shot her once on the right lower shoulder, severing the subclavian artery and causing a severe loss of blood. Critically wounded, Selena ran towards the lobby, leaving a 392-foot (119 m) -long trail of blood. She collapsed on the floor as the clerk called the emergency services, with Saldívar still chasing after her and calling her a " bitch ". Before collapsing, Selena named Saldívar as her assailant and gave the number of the room where she had been shot. Meanwhile, Saldívar attempted to leave in her pickup truck. She was spotted by a responding police cruiser. She surrendered after a nearly nine-and-a-half-hour standoff with police and the FBI. By that time hundreds of fans had gathered at the scene. Many wept as police took Saldívar away.

Selena was taken to the Corpus Christi Memorial Hospital at 12:00 p.m. (CST). Her pupils were fixed and dilated, there was no evidence of neurological function, she had no vital signs, and was declared clinically brain dead. Dr. Louis Elkins, cardiac surgeon, arrived at Memorial Hospital and said he saw doctors making "heroic efforts" to revive Selena. They were able to establish an "erratic heartbeat" long enough to transfer her to the trauma room, and began blood transfusions in an attempt to re-establish blood circulation after opening Selena's chest and finding massive internal bleeding. By the time Elkins arrived, an emergency doctor began "massaging her heart" after it had stopped beating. Elkins reported how all efforts were futile and said had he been the receiving doctor, he would not have made any treatments on Selena. He felt "obligated to continue" after the emergency room doctor made the decision to reanimate the singer. After 50 minutes of surgery, she was pronounced dead from blood loss and cardiac arrest at 1:05 p.m. (CST).

An autopsy was performed on the same day due to the overwhelming media response. It revealed that the bullet had entered Selena's upper right back, near her shoulder blade, passed through her chest cavity, severed the right subclavian artery, and exited her right upper chest. Her official cause of death was described as "exsanguinating internal and external hemorrhage due to perforating gunshot wound" resulting in "massive bleeding". The internal examination revealed that she had not ingested any type of drug, nor was she pregnant, which was a rumor that began spreading after her death.
