The death of woman at Casuarina is being investigated after a postmortem examination identified unexplained internal injuries, NT Police said.

Police director of communications Mark Wilton said the 52-year-old woman was found dead at 11.15pm on Friday on a walking path at the Casuarina Coastal Reserve.

“A crime scene was declared at the time of the incident and while there were no visible signs of trauma, a post-mortem examination has identified internal injuries that have yet to be explained,” Mr Wilton said.

“These injuries have lead to the classification of the case as a suspicious death, with Major Crime Detectives continuing their investigation.”
