A Post Mortem Examination (PME) conducted on the body of 49-year-old Dr Colin Roach found that he died from multiple blunt trauma to the head.
The autopsy was conducted by Government Pathologist Dr Nehaul Singh on Friday morning.
Dr Roach was found in a pool of blood at his Lot 111 Duke Street, Kingston, Georgetown office on Tuesday night by two of his employees who remain in police custody.
His head was bashed in, a COVID-19 vaccination book was placed neatly on his stomach and his unbuckled pants was pulled down to the knees; police also discovered currency on his lower body.
Meanwhile, the prime suspect who was arrested while attempting to flee to Suriname has since confessed to the brutal murder.
Crime Chief Senior Superintendent Wendell Blanhum told the News Room that 19-year-old Hilton Oliver Junior Franklin told detectives that he was the one who inflicted the fatal injuries to the doctor.
The Crime Chief did not divulge further details on the confession, however, police sources told the News Room that the suspect is claiming self-defence.
In his confession, the young man of Best Village, West Coast Demerara, said that he and Dr Roach were imbibing inside his office; he alleged that the doctor took him inside the examination room and pushed him on the bed.
The young man further claimed that the doctor’s trousers were partially off and so, he retaliated by picking up a metal object and hitting the doctor to the side of his head.
Another friend of the doctor who was also there, assisted the main suspect in cleaning up the crime scene, while one of the doctor’s office assistants who live in the same building, removed the DVR that contained the surveillance footage.
The main suspect and his friend then escaped with the doctor’s cellphones and his AUDI SUV which was found abandoned two days later in Schoonard, West Bank Demerara.
Dr Roach worked as the Clinical Advisor for the US Centers for Disease Control and the Public Health Laboratory Director at the Ministry of Health in Guyana; he was also the former Chairman of the National Sports Commission.
The Ministry of Health in mourning his death said the country has lost one of its most experienced Biomedical pathologists.
Dr Roach was part of the pioneering team that began revolutionizing laboratory science in Guyana and was a leading member of the team that began the transformation of manual procedures to automated technology.
PCR (DNA) testing was also pioneered in Guyana by Dr Roach.
At the time of his death, he was in close discussion with the ministry on a new era of transformation for chemical pathology.
Dr Roach is survived by his three children and his wife.
