"The materials that could be used were few!
The murderer must have also used a strap to fix things onto the body of the deceased.
Let me think...
I seem to have seen this type of material before!"
The elder autopsy officer, a black man, fell into contemplation.
The advantage of being older is having seen more and knowing wider.
..
Hearing this, Brian agreed with the elder autopsy officer's deduction in his heart.
The other's judgment was consistent with his own guess.
It also matched with the symptoms of prickly heat.
The strap was tied at the position of the female victim's chest, causing her bra to cling tightly to her skin together with the secretion of sweat and always being covered; the skin of the female victim might have been particularly sensitive, which would explain the occurrence of prickly heat.
This was the most suitable explanation.
The only uncertainty for Brian was the traces of tape used by the murderer; he wasn't very familiar with that aspect.
