'Blood curdling scream': Neighbour heard horrible cries before couple found injured

A neighbour says she had a sleepless night after hearing “blood curdling screams” from a house in Perth’s south.

The Waikiki residence was being combed by WA Police on Tuesday after a man and a woman in their 20s were found with gunshot wounds on Monday about 11.25pm.

Police said the pair are known to each other. Both were hospitalised and remain in a critical condition.

Emma Hull, who lives next door to the pair, told the West Australian she was the one who called police.

She told the paper she heard yelling from the pair who normally keep to themselves.

"It was just a long blood curdling scream that really unsettles you,” Ms Hull said.
