Queensland police struggle to investigate homicide due to lack of CCTV

A lack of security footage is proving to be a stumbling block as homicide detectives investigate the suspected murder of a woman in the small Cape York community of Cooktown.

A body, believed to be that of 42-year-old Donna Louise Steele, was found in Isabella Creek, at Leggett's Crossing.

The waterway is a well-known area for local residents.

Ms Steele had been missing since 02 August 2017, and a search involving a rescue helicopter and the SES had not located her.

The body was found around 20 kilometres from Ms Steele's home, and police are gathering statements from residents.

Four crime scenes have been established, including at Ms Steele's house and a nearby property.

Detective Inspector Geoff Marsh says the lack of CCTV cameras in the town is an 'investigative block'.

Specialist police from Brisbane are at the scene and the dive squad is expected to search the waterway in the coming days.

Ms Steele had two young sons, aged eight and ten, who are now being looked after by their father.

Police do not believe that the attack was random and have revealed that they believe the perpetrator was known to Ms Steele.
