Detectives investigating the suspicious death of a woman whose body was found in an Ipswich home last Thursday believe she had been dead for two weeks before her body was found.

Katherine Sanowski, a 42-year-old woman from Springfield, did not live at the Bellbird Park home on Beryl Court where she was found but was known to the sole occupant, a 34-year-old man who was found by police nearby.

Officers had been called to the street last Thursday after reports of a disturbance around 11.30am, involving a man interfering with traffic in the street.

Detective Inspector Michael Manago said police were treating the death as a homicide.

“We’ve conducted a post-mortem which has identified some suspicious elements in regard to this death and as such we’re treating it as a homicide investigation,” Manago said.

“Our investigations to date suggest that the deceased has been in that dwelling for approximately two weeks so dating back to early February.”

He said the pair were known to each other but not related.

“The dynamics of their relationship remain a key topic of our investigation,” he said.

“We don’t believe there’s anyone else involved but we’re keeping an open mind.”

Sanowski had not been reported missing and there had been no reports of domestic violence between the pair.

Her family has been notified, Manago said, and are “quite distressed”.

The 34-year-old man is undergoing a medical assessment in hospital. He is not under arrest and is yet to speak with investigators.

Officers are appealing for anyone who witnessed anything suspicious at the property or who may have relevant CCTV to come forward.

Police also wish to speak with anyone who knew Sanowski or had any dealing with her in early February.
