Double homicide investigation update from Austin police

FULL NEWS CONFERENCE: Austin police provide an overview of the investigation into the deaths of two people. The suspect, who is custody, was also linked to an AMBER Alert.

On Monday, Oct. 14, at around 3:30 a.m., detectives said Machado pulled behind Francis Kaina Anseume Corredor and Bryan Florentino Flores Alvarez who were parked at Flores’ apartment complex on Burton Drive.

"An individual was observed exiting the vehicle and approaching the passenger side of the white GMC," Austin Police Homicide Unit Detective Matthew Jones said.

About four hours later, "APD received a call for two deceased people in the parking lot," Detective Deluna said.

Anseume and Flores were shot dead.

"It was discovered through the investigation that the victim, the female victim, had three children, all of which were unaccounted for," Austin Police Tactical Intelligence Unit Detective Adam Curvin said. "The primary focus of the investigation turned to the well-being of those children, locating them, and ensuring their safety. To that end, we checked all addresses on record for the couple, the children, and any other address we could identify that had previous APD involvement for that family."

Austin AMBER Alert, double murder suspect arrested

A man in connection to an AMBER Alert for three missing children from Austin and a double murder in Southeast Austin is in custody, the Austin Police Department said.

They said they couldn’t find them, so a statewide AMBER Alert was sent out.

"Within an hour of the AMBER Alert going out, the family with whom the children were with contacted Austin Police Department to notify them that the children were at 5401 Decker Lane and had been dropped off by Machado," Detective Curvin said.

Detectives said Machado was then picked up by one of his brothers. The car was spotted by an undercover officer as it was pulling into an apartment complex off Wickersham Lane. The brother was then seen getting into a different vehicle. He drove to another nearby apartment complex, met up with his other brother, and continued driving.

"Undercover officers with the assistance of APD, Air One unit, continued to follow the vehicle until sufficient resources were in place to conduct a stop on it," Detective Curvin said.

Police said the car stopped in a neighborhood and Machado was arrested.

"Having been found hiding in the backseat of that Kia SUV," Detective Curvin said.
