The case of a woman found dead, naked and decomposing on the kitchen floor of her northwest Tasmanian home has prompted criticism of the subsequent police investigation.

Yugoslavia-born Debbie Dubravka Killer, 67, was found on October 4, 2017, eight days after she was last seen alive and coroner Simon Cooper on Friday explained his struggle trying to determine how or when she died.

Mr Cooper said trying to find an outcome wasn’t helped by how police reacted at the scene, but concluded the death was likely not suspicious.

On entering Ms Killer’s home via a window after finding all doors were locked, police noticed some “upset items” in the kitchen before discovering her body.

Mr Cooper questioned why police didn’t take any photos, which could have been done “very easily with a mobile phone”.
Police also failed to call in forensic help.

“The absence of any photographs and any forensic evidence at all compromised the coronial investigation,” Mr Cooper said.

“Police subsequently claimed that the need to photographs did not fit with any of the categories in the Tasmania Police manual.

“I cannot accept that at the time, suicide or murder could or should have been ruled out.

“My investigation of Ms Killer’s death has been hampered by the manner in which the investigation was conducted.”

A regular church-goer, Ms Killer was described by the last person to see her alive as a busy artist who was active member of the Smithton community.
