Authorities say Marquez had no knowledge of or role in the attack.
The sentencing for Enrique Marquez Jr., the Riverside resident convicted of purchasing the weapons used in the Dec. 2, 2015, San Bernardino shooting, has been postponed.
The sentencing in U.S. District Court in Riverside had been scheduled for Tuesday, Nov. 6. The hearing is now scheduled for Feb. 26.
Marquez agreed to a plea deal that could imprison him for the statutory maximum sentence of 25 years to life in federal prison and a $500,000 fine.
The defense, in court filings, expressed concern over the timing. The request for a continuance cited the approaching anniversary of the slaying of 14 people and wounding of 23 others at the Inland Regional Center, and the fact that recently, on Oct. 1, 58 people were killed and more than 500 were injured in the Las Vegas shooting.
The filing also noted that federal prosecutors announced plans to have a terrorism expert attend the sentencing, and that defense attorneys might want to produce their own expert. Additionally, defense attorneys said, the government recently said there were additional reports available for review, and the attorneys needed time to examine them.
In opposing the postponement, prosecutors argued, among other things, that victims and families of those who died in the San Bernardino shooting have been counting on the case against Marquez being resolved on Nov. 6, and that prosecutors doubted the timing of the sentencing would affect the length of the prison term to be handed down by U.S. District Judge Jesus G. Bernal.
Marquez on Feb. 16 pleaded guilty to providing material support to a terrorist and making false statements in connection with the purchase of firearms.
Authorities have said that Marquez conspired with San Bernardino shooter Syed Rizwan Farook to plot attacks in Riverside that were never carried out. Marquez lied on federal forms that he was purchasing the firearms for himself when in fact they were given to Farook.
Farook and wife Tashfeen Malik, Redlands residents who had been radicalized, carried out the attack in San Bernardino before being shot to death hours later in a gun battle with police.
