A woman has been refused bail after being charged with the stabbing murder of an American man in Sydney's south-west.
Emergency services were called to a Cecil Hills home just before midnight last night, after hearing reports a man had been stabbed.
When they arrived, they found a 32-year-old US citizen with chest injuries.
He was rushed to Liverpool Hospital by ambulance but died a short time later.
A 31-year-old woman was arrested at the home and has since been charged with murder.
She faced Parramatta Bail court this morning and was denied bail.
Police say the man and the women were known to each other.
