The Marshals Service had said incorrectly Wednesday that Olaguez was being immediately handed over to Mexican officials. But on Thursday, officials said they were debating how and when to return him to Mexico.
Olaguez, 53, was one of four people arrested in January in connection with four marijuana grow houses in Stockton, 50 miles (80 kilometers) south of Sacramento. Authorities found more than 900 marijuana plants and nearly 30 pounds (over 13.6 kilograms) of marijuana that was being prepared for sale, Turner said. They also found a gun, the prosecutor said.
Two of the other defendants in the marijuana-cultivation case are believed to be Olaguez's wife and his brother, Turner said.
Olaguez remained in San Joaquin County Jail until April, when he was released on his own recognizance because of jail overcrowding, Turner said. A warrant was issued for his arrest when he failed to show up for a court appearance April 22.
There was no effort to track Olaguez's whereabouts until a Sacramento-based law enforcement task force led by the Marshals Service found out in September that the Mexican government was seeking Olaguez in the slayings and he was living in the U.S.
The task force learned Tuesday that Olaguez was living with relatives in Sacramento and made the arrest, said Deputy U.S. Marshal Frank Newsom.
Olaguez's oldest son, Jair Olaguez, 18, told The Sacramento Bee he was confused by his father's capture.
"I think they got the wrong person," he told the paper. "He didn't kill no one."
Olaguez used a Spanish interpreter when he was arraigned in San Joaquin County on Thursday for failing to appear on the charges of marijuana cultivation, possession of marijuana for sale and theft of utilities. He was being held in lieu of $1 million bail on the state charges while U.S. and Mexican authorities decide the next step.
Virginia Kice, a spokeswoman for U.S. Immigration and Customs Enforcement, said Olaguez would be held for immigration authorities even if he posts bail. Federal authorities could obtain a warrant from Mexico and attempt to extradite Olaguez or seek to deport him administratively.
Kice said she didn't know Olaguez's immigration status.
Turner said there was no indication that Olaguez is in the U.S. illegally and he has a clean criminal record in the U.S. based on his fingerprints.
The Mexican Consulate in Sacramento did not comment despite repeated requests over two days. Olaguez is scheduled to return to court Dec. 19.
