"So our victims were allergic to silver which caused the chemical burns when they were decapitated?"

 

(Excerpt Alma Introduction)

 

Wearily, she rubbed her eyes which were sore from looking at computer screens all day.  She envied Griggori since he was a Detective, he could leave the building and get some fresh air once in a while.  Her work was scanning samples on glass slides then analyzing the results.

            "There are more murders that occurred in Russia which are related to our OO Positive suspect," she sighed tiredly.

            "More?" he echoed in surprise. 

            Julia hit a new command on the computer and pictures of twelve bodies appeared on screen.  Nine bodies had been decapitated and three victims were missing most of their heads, which looked eaten away.  Even Griggori had to flinch at the gore, with blood spatter, bits of skull and some brain matter surrounding what was left of their heads.  Then he caught the date on this case file, it was the year 2145 again.

            “These bodies were all found at a crime scene in St Petersburg.  Nine were beheaded by a sharp, metallic weapon, like a sword.  The weapons were most likely in the style of the Japanese Katana, as they are light-weight but strong and extremely sharp.  Do you see the cuts?”

            “They’re clean," he nodded along with her.

            “But look here at how the flesh is singed slightly.  Forensics first thought the swords had been heated to burn the flesh so.  But when they ran further tests, it showed that the flesh was not singed by heat, but they were chemical burns.  There were also traces of silver in the wounds, meaning the Katanas were coated in silver."

            "So our victims were allergic to silver which caused the chemical burns when they were decapitated?" he summed up.

            “Correct, now don’t interrupt me," she playfully whacked him on the arm.  “Or I will pack up my test tubes and Petri dishes and go home.”

            “No, don’t do that, Babushka," he pretended to be alarmed.

            “The twelve victims all had OO Negative blood type," she announced. 

            "Really?" he sat back on his stool, to take it all in.

            "The OO Positive middle-aged man that died by a sword to the heart, he too showed chemical burns around his wound."  She continued.  "I believe the same person or persons, with silver-coated Katanas, murdered that man as well as the nine OO Negative victims."
