MIAMI — A federal grand jury on Thursday indicted an Alaska resident accused of going on a shooting rampage at a Florida airport this month, leaving five people dead and six others wounded.

The 22-count indictment charged the man, Esteban Santiago, 26, with 11 counts of causing death or bodily harm at an international airport, five counts of causing death during a crime of violence and six counts of using a firearm during a crime. Mr. Santiago could face the death penalty if convicted in the shooting, which occurred on Jan. 6 at Fort Lauderdale-Hollywood International Airport.

None of the charges are terrorism-related, despite Mr. Santiago’s assertion to the F.B.I. after the shooting that he was inspired by videos and chat rooms affiliated with the Islamic State extremist group. The F.B.I. has said that Mr. Santiago also claimed to investigators that he was the victim of government mind control.

Mr. Santiago, an Iraq war veteran who lived in Anchorage, is scheduled to enter a plea on Monday and is being held without bail.
