A jury has heard a recording of a 999 call made by a woman, allegedly attacked by a man who stalked women at bus stops, who could be heard crying.
A pub landlord told the Old Bailey how he found Irma Dragoshi lying on a road near Heathrow airport in pain with a bump "as big as an egg" on her head.
When Clifford Hare called 999 she could be heard wailing in the background.
Levi Bellfield, of West Drayton, west London, denies two murders and three other attacks between 2001 and 2004.
Albanian-born Mrs Dragoshi, who is a hairdresser, was 33-years-old when she was attacked in Longford village, west London, on 16 December 2003.
Giving evidence Mr Hare said he was returning home from his pub, the White Horse, in Longford village in December 2003 when he found the victim lying on the road in the bus stop.
He initially mistook her for "a roll of carpet", he said.
"It moved. That's when I realised it was somebody lying there."
"She was in distress and was hurt. She was crying and confused. I helped her to her feet.
"There was a large bump on the back of her head, as big as an egg," he said.
In the tape played to the jury Mr Hare could be heard telling the operator that the woman had been mugged and she wanted to get into a bus as she felt safer there.
Mrs Dragoshi's wails could be heard in the background.
Mr Bellfield, a former nightclub doorman and a wheel clamper, denies murdering students Amelie Delagrange, 22, in August 2004, and Marsha McDonnell, 19, in February 2003.
He also denies the attempted murders of Kate Sheedy in 2004, and Mrs Dragoshi in 2003, as well as causing her grievous bodily harm.
Mr Bellfield further denies the kidnap and false imprisonment of Anna-Maria Rennie in October 2001.
The trial continues.
