Body Found at Cooper’s Furnace Angelica Shannon D.S.W. , Jordan Burge M.S.F.S. , Jahidi Solomon FOP, Christian Mauldin BFor.Od. Department of Forensics and Forensic Pathology

Case Summary: An 18-year old white male was discovered by a hiker on the Cooper’s Furnace Hiking Trail in Bartow County at 5:30 pm. He was bound with rope and partially covered with leaves. Officers also found a tire iron nearby that is believed to have been the murder weapon. The body was found by a passing hiker. They then proceeded to call 911. The first officer arrived at the scene at 5:40 pm. After securing the scene, investigators proceeded to take multiple photographs of the scene. Evidence collected included: the victim, multiple hairs, a red fiber, and a tire iron. Results and Discussion: Upon field examination, the body, later identified as Carl Grimes, was in the beginning stages of lividity and rigor mortis with only the face and neck becoming rigid. Further examination revealed a lone hair in the hand of the victim. The tire iron was found to have traces of blood and a cluster of fibers caught in its middle portion. The body was then sent to the forensic pathologist for an autopsy to determine the cause and mechanism of death. The pathologist concluded that the cause of death was a homicide caused by blunt force trauma to the upper-left portion of the skull.

This led to cranial fracturing, cerebral lacerations and eventually intracerebral hemorrhaging, which ultimately led to the victim’s death. The pathologist also concluded that the time of death was approximately 12:00pm. This was determined through examination of the state of the body at the time of discovery. Several witnesses claimed that the victim was last seen walking southeast on Old River Road at approximately 11:45 am. The police have named several suspects that were placed on the hiking trail around the time of the homicide. The police immediately searched for people that were close to the victim. In their search, they discovered that Jessica Baldwin was seen with the victim around his time of death.

Fingerprint analysis was a confirmed match between Jessica and the murder weapon. In addition to this, fibers from Jessica’s purse were a match to the fiber found at the scene. After searching Jessica’s car, a bloody t-shirt was found in the trunk. Through the use of a presumptive test and blood typing test, it


was concluded that the blood matched that of the victim.

Conclusion: Multiple instances of physical evidence, including fingerprints, hair, fiber, and blood led to the arrest of Jessica Baldwin on one count of second degree murder.

Microscopic Analysis of Fibers Introduction

Based on the results we have found we have concluded that the fiber is one of natural nature. Our analysis has found that the fibers do indeed seem to match the fibers on the purse of Baldwin. However, because of the multitude of natural fibers we must conclude that the evidence is simply one of class nature, and cannot call it individual, despite its unique color and overall look of the fiber that did have us slightly befuddled.

We suspect from our previous results that the fiber will burn in a way that a natural fiber does, and that as it approaches the flame it should burn quickly and should leave behind a white fluffy residue after being burned.
