Homicide victim Stephen Cobb suffered serious trauma to his brain and internal bleeding before he died, according to the full autopsy report.
Cobb, 29, of Sandusky died in October, eight days after he was found unconscious and lying in a pool of vomit on the corner of McDonough and Water streets. His death was ruled a homicide, caused by trauma to his brain stemming from an assault.
Two teenagers, a 15-year-old boy and William I. Keyes, 19, are both charged with murder in the case. Keyes is additionally charged with involuntary manslaughter, aggravated robbery and felonious assault.
Cobb was suffering from pneumonia at the time of his death, but that was not a contributing cause, according to the Lucas County coroner's autopsy report.
A blow to the back of Cobb's head left a half-inch cut. Police have not yet revealed what sort of weapon was used in the attack.
The blunt force caused extensive brain hemorrhaging. There was indication doctors tried to save Cobb by placing a bolt in his scull near the wound to monitor pressure in the brain cavity.
No injuries, bruises or cuts were found on Cobb's hands, the report said.
A neuropathology report conducted by Akron neuropathologist Dr. Dimitris Agamanolis revealed Cobb's brain was swollen on one side. His report stated internal pressure from inside the skull near the lesion contributed to Cobb's death.
In related news, a mental competency evaluation has been requested for the 15-year-old, who is charged as a juvenile. A prosecutor is also asking his case be bound over to adult court. Keyes awaits a pretrial hearing Feb. 4 in Erie County Common Pleas Court.
