Sisters claim they heard 'Australians screaming for life' on night Balinese police officer was 'murdered'

Two Sydney sisters claim they heard "Australian voices screaming for their life" while staying in a Bali hotel across the road from where a local police officer was murdered.

Coleen Bowen and Kim Watson told The Courier Mail that they believe the screams they heard while staying at the Pullman Hotel in Bali were related to a fight that lead to the death of police officer Wayan Sudarsa.

Sara Connor, 45, and her British boyfriend David Taylor, 34, are accused of murdering officer Sudarsa whose bloodied body was discovered on the morning of August 17 on Kuta Beach.

The Byron Bay mother-of-two and her boyfriend were arrested on August 18 and have been held at Denpasar Police Station.

Ms Watson and Ms Bowen said they were too scared to tell Balinese authorities about what they heard that night and returned home to tell Australian Federal Police (AFP) to avoid becoming embroiled in the case.

Ms Bown said she and her sister woke to screams of desperation at around 1-1.30am.

"I heard this screaming that woke me up," Ms Bowen said. "It made me jump to my feet. I opened my curtain, I was scared, I didn't want anyone to see me.

"I sat on the edge of my bed for a little while. I was shaking."

Ms Bowen said the voices sounded Australian and said she heard a female scream: “No, no, let him go."

The sisters said they both heard a male voice yell: “No, don’t do that you f-----g c---”

Ms Bowen claimed she "didn’t hear any Indonesian voices" and said the two Australian voices sounded as though they were being attacked.

The following morning, the sisters woke to see their hotel cordoned off with police tape and subsequently learned Ms Connor and Mr Taylor were main suspects in a police murder.

Peter Strain, Ms Connor's Australian lawyer, said the the sisters' evidence was consistent with what his client has told Balinese police in numerous police interrogations.

Ms Watson and Ms Bowen said no authorities approached or questioned hotel guests about the incident.

Ms Connor claimed she did not know the police officer was dead because she was told he had passed out.

The mother and her boyfriend have both maintained they did not realise officer Sudarsa was dead and claimed they planned to contact AFP once they were home.
