Apologies for this lengthy post.
Warning: The paragraphs following the second link are extremely graphic.
After accessing the data on the BM’s phone, detectives discovered that BM had sought information online on “… what kind of plastic can stand (muriatic) acid”. On March 4 he went to a Home Depot store and purchased four gallons of muriatic acid.
On the same day he bought a 32-gallon Brute trash can from Lowe’s Home Improvement Center. These trash cans are “constructed of professional-grade plastic, a durable and flexible polymer that's nearly indestructible; this material was chosen over metal because it won't rust or corrode”.
The trash can he bought matched one located by police.
The court document explained police hired a plumbing company to assist them in conducting a search warrant at the residence. That plumber removed the P traps from the home's bath tubs, bathroom sinks and kitchen sink. The plumber told investigators that the P trap for the tubs appeared cleaner than a normal P trap considering the age of the building.
Other evidence that led to the charges against McIntosh include data from his cellphone, computers, electronic devices, and storage devices.

LE obviously believe that Noah was murdered in the bathroom and BM was charged even though they had not found a body. I couldn’t help but wonder what exactly LE found in the bathroom and then I had an idea. Some sleuthing revealed the following:
2009 Journal of Forensic Dental Sciences.
“… destroying the human body by immersing it in an acid …in order to avoid any personal identification is drawing a great deal of forensic interest these days. Crimes of this nature have been frequently reported in Italy.
The results showed that teeth could be completely dissolved in 37% hydrochloric acid after 15 h of immersion.
Hydrochloric acid, nitric acid and sulfuric acid cause changes in the teeth and it is possible to deduce the approximate duration for which a body has been immersed in acid based on the charges observed.
The identification of dental remains is of prime importance when the deceased person is skeletonized, decomposed, burned, or dismembered.
It is possible to destroy the human body completely in an acid. In crimes of this nature, hydrochloric acid is the most commonly used acid. Morphological changes in teeth can help the forensic investigator to deduce the time elapsed since immersion of the body in the acid. By keeping in mind the likely choices of the criminal and by observing the morphological changes in the teeth, it may be possible to deduce which acid has been used to destroy the body.
Since the natural teeth are the most durable of all tissues, they can persist even long after other skeletal structures have been destroyed by physical agents.

The results of this study have been published in other articles but I would have had to supply my email address. I hate to think of what’s already on my PC so I wasn’t going to do that.
I believe BM filled the trash can with muriatic acid, dismembered the body and placed it in the trash can until the flesh had dissolved. He then poured the liquid down the drain but placed large bones, if any remained, back into the empty trash can which he took to the location where it was found.
However, teeth
may have been recovered from the P trap/s as there’s a good chance they hadn’t been in the acid long enough to completely dissolve.
