The weapon is a letter opener like this one. I just need advice on how the victim would loo in terms of bleeding, etc. Blood from the mouth or nose? Eye response of some kind? Would death be immediate, most likely?
Bleeding was said to have been minimal but an ice pick is smaller than a letter opener.When carrying out murders, his weapon of choice was an ice pick, which he would ram through his victim's ear right into the brain. Reles became so adept at using the ice pick that many of his murder victims were thought to have died of a cerebral hemorrhage.
Your eardrum is exsquisitly sensitive to pain.There are a lot of horror stories about the Japanese death-marches during WWII, this is an excerpt from an interview with an Australian POW.
"The interviewer produced a small piece of wood like a meat skewer, pushed that into my left ear, and tapped it in with a small hammer. I think I fainted some time after it went through the drum. I remember the last excruciating sort of pain, and I must have gone out for some time because I was revived with a bucket of water. Eventually it healed but of course I couldn’t hear with it. I have never been able to hear since."
Hopefully that helps describe the experience. But we're talking a stab into the brain. I'm no expert, but a stab to the brain via the ear canal would probably end with the letter opener being somewhere in between the cerebral cortex (Balance and coordination) and the brain stem (breathing, reflex movement, regulation of heartbeat, consciousness, and a lot of other really important things) So if the man doesn't die instantly (which isn't necessarily an uncommon occurrence) he'd probably fall to the ground and clumsily fumble around for a few seconds trying to grasp the letter opener, maybe some inhuman groans, moaning, or hiccup-like gasps for breath involved before he'd eventually lose consciousness and die from the blood and swelling destroying the brain stem. Hopefully that helps.
