Police Divers Scour River For Baby Murder Clues

Police investigating the murder of a nine-month-old baby girl whose body washed ashore on a Gold Coast beach cannot rule out charging her mother over the death.

More than a week after the baby was killed, a major land and water search is underway as officers scour the Tweed Heads River and surrounding areas for evidence.

NSW Police want to find a red and black picnic-style blanket that could have washed ashore somewhere between Tweed Heads and the Gold Coast.

Detectives believe the baby girl was drowned in the area of the Jack Evans Harbour at Tweed Heads between 6pm and 7pm on Saturday, November 17.

The girl's body is believed to have drifted for almost 30 hours before washing ashore on Surfers Paradise Beach, where it was found just after midnight on the following Monday.

Her father, who cannot be named for legal reasons, has been charged with murder and appeared by video link in Tweed Heads Local Court last week.

NSW Police Chief Inspector Wayne Walpole said Monday's tidal conditions were similar those on the night of the girl's death.

Water police and divers will search the Tweed River and foreshore areas while others scour foreshores and parkland around Jack Evans Harbour and Cunningham Park.

Police are conducting dives in line with tidal and current flows to try to determine what happened on the day of the incident.

They are also asking for anyone who was in the area on the night of November 17 to come forward.

Insp Walpole said there was significant storm activity on the night the girl died and appealed to any storm watchers who may have seen the baby, her parents, or her older brother to contact police.

Police have obtained CCTV footage from surrounding high-rise buildings and also want to hear from anyone who might have mobile phone or dash cam footage taken in the area.

"We are interested in speaking to anyone who has seen those people or had interactions with those people to come forward," Insp Walpole said.

"We would ask for anyone who thinks they saw something, they might not think it's important or significant but a very small piece of what they see could be very important to the investigation."

Asked if the girl's mother could be changed, Insp Walpole said the investigation was ongoing and it could not be ruled out.
