NSW woman begged intruder not to kill

A distraught woman begged a masked intruder to stop his "crazy" accomplice from going into her daughter's bedroom during a violent NSW home invasion.

Alana Bush told a Sydney jury on Tuesday that when the intruder replied "Nobody's going to get hurt" she gestured towards her bleeding and convulsing husband and said: "He's going to die."

The couple's hands and legs were tied and, as a pillowcase was put over her head, Ms Bush begged: "Please don't kill us."

Ms Bush was giving evidence at the NSW Supreme Court trial of Ryan David Evans, 28, who has pleaded not guilty to seven charges related to two home invasions.

He is accused of savagely attacking Ms Bush's husband, Brett Delamont, with a pick handle at their Medway home in the NSW Southern Highlands in the early hours of April 28, 2014.

One month later, on May 20, he allegedly murdered pig farmer Keith Cini and wounded his partner, Lucina Boldi, with intent to murder her at their Badgerys Creek home in Sydney.

The Crown alleges Evans and two other men were involved in the Medway invasion, one of whom had previous contact with the family and knew the house layout.

Ms Bush has testified she woke up to find two masked men in her bedroom with her husband, suffering an injured and bloodied head, convulsing beside her.

One man yelled at her to stop screaming, saying "shut up, or I'll hit him again" before he lunged and hit across the bed where her husband was lying.

Asked who else was in the house, Ms Bush eventually told him her daughter, Kirby Delamont, and her boyfriend both were.

The first intruder left while the other man stayed.

"I asked him to stop the crazy guy going into my daughter's bedroom," Ms Bush said.

When the second man said nobody was going to get hurt, Ms Bush stated: "Look at the hole in his (her husband's) head."

"We need help ... he is bleeding, he is shaking, he is going to die."

The man later told her: "This is not personal, it's random."

Ms Delamont says she woke to hear her mother screaming.

Two masked figures appeared at the bottom of her bed, one holding a pole-like weapon and the other a light.

"Their faces weren't visible, they were covered by something," she said.

One man yelled at her and her boyfriend to "get under the covers" before their wrists and legs were tied and he said: "I will be softer on you, sweetie."

The trial is continuing.
