A man who was allegedly driving while his licence was suspended has been charged following a fatal hit-and run in Sydney’s south-west at the weekend.

Natasha Gadd, 19, died when she was struck by a ute on Henry Lawson Drive at Milperra just after 4am on Sunday.

Police found the white Toyota Hilux they believed was involved in the incident at a factory at St Peters last night.

A 35-year-old man was later arrested at a home at Old Guildford.

He has been charged with several offences including dangerous driving causing death and driving with a suspended license.

The man has been refused bail and will appear at Fairfield Local Court today.

Detective Inspector Katie Orr said police will allege the man struck Ms Gadd while she was walking with friends.

“We hope this provides some closure, they’re aware of the arrest and although it won’t bring their daughter back, we hope it’ll provide some closure for the family,” Detective Inspector Orr said.

“They’re obviously very distraught still.”

‘I never knew heartbreak until today’

Paramedics attempted to resuscitate Ms Gadd at the scene but were unsuccessful.

Almost $20,000 has been raised on a GoFundMe page to support her family.

Ms Gadd’s family and friends have remembered her as “one of a kind”.

“She was intelligent, always smiling, a best friend to many and she was truly one of a kind,” one online tribute read.

“Any death is sad in itself, but losing the rock of your family has absolutely shattered her loved ones.”

Another family member said their “tears won’t stop”.

“I can’t believe ur (sic) not coming home, the tears won’t stop I love you so much,” they posted.

“I never knew true heartbreak until today.”

Drivers obliged to render assistance

Police warned the public to stop if they hit a person while driving.

“If you do hit someone, you’re obliged to stop and you’re obliged to render assistance,” Detective Inspector Orr said.

“I would advise not to drive away.”
