An arsenal of weapons and ammunition found in a Waikiki hotel room landed a man in the hospital, but not in police custody.

We’re told a 38-year-old man had posted “suspicious messages” on social media, prompting the FBI to ask HPD to perform a welfare check. 

Police tracked him down Thursday night and, upon arriving at the hotel room, found the guns, 18 knives, and more than 800 rounds of ammunition and shotgun shells.

Investigators also found bulletproof vests, camouflage uniforms, a mask, and psychiatric medications in the room.

The man, who is a local resident, told police he brought all of the weapons and ammunition to the hotel room over the course of a few days.

Police found all of the guns were registered to the man. The weapons were confiscated. 

In an email response, the Honolulu Police Department said: 

“HPD officers responded to a report of a suspicious male in Waikiki yesterday.  The male was located and taken to a hospital for evaluation, where he remains.  No charges have been filed at this time.

Investigators recovered the man’s belongings, which included firearms and knives.  HPD and FBI investigators are continuing to work on this case, and no further information is being released at this time.”

The FBI told KHON2 it is aware of the suspect, but declined to comment because it is not the lead investigator in the case.
