Puzzletober 2025: Vacant

It is roughly noon on the first day of November. The patrons have checked out and all but two of the rooms are vacant. In the suite labeled with the number one, someone awakes with a start. He had stayed up late trying to make sense of all the information that had been given to him. After all, he had an obligation. On his bedside table is an old flyer turned upside-down. Many words are written on it, but there are several blanks. He knows how to fill them in. As swiftly as he can, he clutches the flyer and ambles over to the room at the end of the hall. The door is unlocked; he goes into the connected bedroom and finds the innkeeper and the clerk lost in sorrow sitting on the bed.

"I even barricaded the door," says the innkeeper. The newcomer anxiously scans the room for a writing implement and, not finding one, decides to explain it as he goes. "I think I know who did it. Let me read my statement from the beginning."

Rules: Solve the mystery. Each bracketed section may be replaced by one appropriate word. (For the general prompts, you may choose any word that fits, but for an optional challenge and a little hint, it is possible to replace all but three or four of the prompts with words that were typed previously in the narrative.) "OR" represents a choice. Text in quotations within bracketed expressions after resolving any inner brackets must be used verbatim if selected. 

"I was hired to ["assist" OR "be" OR "catch"] the criminal responsible for the disappearance of the [noun] from the [noun]. The crime took place in the ["event" OR "storage" OR "[occupation]'s"] room. They made a [noun] in the [noun] and removed the [noun] of the [noun] by [verb] the [noun] that kept it secure. To cover their tracks, they returned everything to the proper positions, [verb] the [noun used in "...made a [noun] in the..."], and finished with the [adjective] [noun]. This would explain why it was so [adjective] despite there only being one room in the [building] where it would be useful. Ordinarily, I would blame the [occupation], [first name] [last name]. But, the [occupation] was [word] today. However, we did discover recently that the [occupation] was able to [verb] that [noun], and, apart from the [occupation], was the only person able to do so last night. Therefore, I am certain that [first name] [last name] is the person responsible. Sincerely, the man you knew as [first name] [last name]."
