Part 2 of voat's investigation into Heather O'Rourke murder. Part 1 is linked in thread too.

Voat looked into the Standard Hotel Acid incident.

A standard bathtub can contain 30-40 gallons of liquids.

20 gallons is enough to completely submerge an adult in liquid.

This gives me the deduction that if the acid is related to disposing of corpses, then about 5 bath tubs were used for this evidence destruction.
