In the meantime, statements have been taken and the murder weapon was recovered and has been sent for analysis at the Guyana Forensic Science Laboratory.A post-mortem examination (PME) conducted on Lyttle’s body by Government Pathologist, Dr Nehaul Singh on Thursday revealed that he died as a result of multiple blunt trauma to the head.
