A female Royal Navy officer who was found dead on board a warship at Devonport Dockyard in Plymouth died of natural causes, police have said.
Lt Douglas first served as an engineer on HMS Ark Royal
The body of deputy marine engineer Lieutenant Emma Douglas, 29, from Huntly in Aberdeenshire, was discovered on 3 October on board HMS Cornwall.
The findings of toxicology and other tests have been sent to the coroner.
Lt Douglas was described as being well respected and a "bubbly character" by navy colleagues.
A cremation service was held last month and her ashes were scattered at sea.
Lt Douglas joined the Royal Navy in 2000, serving first as an assistant marine engineer on HMS Ark Royal.
She had also fenced for the Royal Navy Amateur Fencing Association.
