answered and was the last time Pérez spoke to his wife. At the motel room, Selena and Saldívar began arguing. Motel guests complained about loud noises coming from Saldívar's room. They said they heard two women arguing about business matters. Selena told Saldívar she could no longer be trusted, and demanded Saldívar to return her financial papers. Selena then dumped Saldívar's satchel containing bank statements onto the bed and saw the gun. At 11:48 a.m. (CST), Saldívar pointed it at Selena. As Selena tried to flee, Saldívar shot her once on the lower right shoulder, puncturing an artery and causing a massive loss of blood. Trinidad Espinoza, the hotel's maintenance man, reported hearing a "loud bang", which he likened to a car engine misfiring. Selena was critically wounded.
