Forensic reports have confirmed that murdered Japanese pannist Asami Nagakiya was not sexually assaulted before she was strangled in the Queen's Park Savannah last month.
Police sources working on the case told the T&T Guardian that samples sent for further testing abroad were returned last week and debunked suspicion that the 30-year-old had been raped and murdered.
The samples sent for testing also included oral swabs, which police said revealed some "very useful information" as they were awaiting analysis of DNA samples taken from suspects for comparison.
Nagakiya's body, still dressed in her Legacy Carnival costume, was found around 9.30 am on Ash Wednesday (February 10) under a tree at the Queen's Park Savannah by a homeless man. Nagakiya, a trained musician by profession and a tenor player with PCS Silver Stars, arrived in Trinidad on January 8 to participate in Carnival.
Homicide officers detained one man for questioning for three days before he was released while others gave statements to the police.
Investigations are continuing.
