The Halloween Zombie Attack of 2014- A Case Study in Forensic Serology Holly J. Hawkins and Sarah E. Davidson Department of Forensic Science Cass High School, White, GA.
Case Summary: Halloween at Cass High School was recently taken to an entirely new level. At 11:34 a.m., the attack of the zombies began. More than 5 zombie like people began to bombard the school. Luckily for the students, Mr. C. Bohannon’s class had been outside studying Serology. Upon noticing the attackers, each student took up arms and began killing the zombies. One by one, the zombies died, thus saving the school, and possibly the world, from a zombie outbreak. The CDC is currently investigating what caused this, due to the overwhelming amount of people worried that it could be a side effect of Ebola, the most popular new virus in today’s world. This study will cover the Serological analysis of one of the zombies, which has now been identified as Marianna, a young football player with hopes of moving home to China within the month.
Pictured are several smashed zombie heads (right) and the girls responsible for smashing Marianna (left). The picture was taken prior to smashing the head, but after the beheading.

Discussion of Results: At the scene, there were many puddles of colorful zombie blood. One in particular, from Chinese football player, Marianna, was reddish-pink in color. This blood was analyzed and the results showed many important facts about the killing that day. From Marianna’s murder, there was a large pool of blood, and many smaller puddles surrounding it. Investigators chose forty-five different blood drops from this scene to analyze. With this, they determined the width and length of all the drops, the R value, the angle of impact, tangent of the angle, distance from the point of convergence, and the height Marianna was at when she was killed. Analysis showed that Marianna was beheaded and then her head was smashed with several different objects. When the investigators drew the lines of convergence, it showed that the head was hit five different times. Pieces of the skull were found in the blood spatter, proving this to be a brutal murder. After finding multiple points of origin, investigators were led to think that the head was hit, moved back to its original position, and then hit again. The assailant is believed to be around 5.5 feet tall, due to the different heights the blood spatter came from.
