Maui Man Arrested in Connection with IED

HONOLULU – Robert Francis Dumaran, age 47, of Kahului, Maui, made his initial appearance in United States District Court today before United States Magistrate Judge Kenneth J. Mansfield, following his arrest pursuant to a criminal complaint for possessing an unregistered destructive device and attempting to damage property by means of explosives. A preliminary hearing is set for August 27. He was ordered detained without bail.

The complaint and affidavit allege that on July 23, 2024, Maui Police Department (“MPD”) officers encountered an improvised explosive device (“IED”) near Lono Avenue in Kahului. The IED was in the roadway by Kahului Elementary School. The IED contained explosive powder, a battery, and shrapnel. Dumaran’s fingerprints were recovered from packing tape used to build the IED.

If indicted and convicted of the charged offenses, the defendant would face up to ten years in prison on the unregistered destructive device charge and a mandatory minimum sentence of five years in prison and up to 20 years on the explosives charge. The charges and information contained in the federal complaint are merely accusations, and the defendant is presumed innocent unless and until indicted and proven guilty beyond a reasonable doubt in a court of law.

The affidavit also mentions the recovery of detonated IEDs near Kaamana Street in Kula on August 7, and the explosion of an IED and resulting damage to a car in Pukalani on August 8. The complaint does not charge Dumaran in connection with either of those events.

The FBI and Maui County Police Department conducted the investigation resulting in the complaint and arrest, and the investigation into these matters remains ongoing. The prosecution is being handled by Assistant U.S. Attorneys Wayne Myers and Jonathan Slack.
