A man arrested on suspicion of plotting to bomb a historic Colorado synagogue is set to be back in court.

Richard Holzer is scheduled to appear in federal court in Denver Friday for a hearing to review the evidence against him and determine whether he should be released from jail.

The 27-year-old was arrested Nov. 1 after the FBI said he accepted what turned out to be phony explosives from undercover agents he had been talking to about the plan to bomb Temple Emanuel in Pueblo.

An undercover agent began talking to him on Facebook in September after investigators say he promoted white supremacy and violence on several accounts.

Holzer is represented by an attorney from the federal public defender’s office, which doesn’t comment on its cases.
