Officers found Natalie Tavares, 18, with a gunshot wound about 3:50 a.m. next to a vehicle at the Tiger Cabaret Club on Interstate 30 near Buckner Boulevard.

Witnesses told police Aldo Saucedo, 19, had been fighting with a man inside the club. He left and pulled his vehicle to the front of the club. Tavares stood by the driver's side talking to Saucedo.

That's when a man approached Saucedo's car and punched him, according to an arrest warrant affidavit. Saucedo grabbed his gun and shot at the man but struck Tavares multiple times, police said.

Saucedo got out of his car and continued to shoot, according to the arrest warrant affidavit. Investigators said he shot another woman, who was hospitalized with injuries not believed to be life-threatening.

Saucedo ran after the man who hit him and kept shooting, police said. They don't know if the man was injured.

Tavares was taken to Baylor University Medical Center at Dallas, where she was pronounced dead.

Saucedo faces charges of murder and aggravated assault. He admitted to discharging his gun in a voluntary statement to police, according to the arrest warrant affidavit.

His bail has been set at $1 million.

Tavares' family will host a candlelight vigil outside Tiger Cabaret at 8 p.m. Monday. The family will raise funds to cover funeral expenses and help care for Tavares' son.

Saucedo is the boy's father, but Tavares' family wants nothing to do with him, said Dezarai Trevino, a friend of the family.

"How can you not know what you're doing ... and shoot the mother of your child?" Trevino said.
