(December 12) Joseph Castorena, the suspect in the Oct. 30 quadruple homicide in Aurora, was arrested over the weekend in Mexico.

Castorena, 21, was arrested Saturday, December 10, 2022, in Aguascalientes, a state in north-central Mexico, with the assistance of the FBI, local police officers in Mexico, the Instituto Nacional de Migracion – Mexico’s immigration enforcement agency – and the Mexican government. Castorena was flown to the U.S. Sunday and was booked into a Maricopa County Sheriff’s Office detention center located in Phoenix.

Following the Oct. 30 quadruple homicide, investigators with the Aurora Police Department’s Fugitive Unit developed information Castorena fled to Zacatecas, another state in north-central Mexico. Investigators, with the help of federal and Mexican law enforcement partners, continued to monitor Castorena’s movements south through the country until his arrest Saturday.

“The arrest of Joseph Castorena should serve as an example that the dedicated men and women of the Aurora Police Department never quit on a case until those responsible are in custody,” said interim police Chief Art Acevedo. “I would like to thank our federal partners at the FBI and our law enforcement partners in Mexico for teaming up on the arrest.

“We hope this announcement helps bring family and friends of the victims a little closer to the closure they deserve.”

It’s not yet known when Castorena will be transferred to Colorado.
