Louise Miller sobbed as she read out her victim impact statement at today’s Downing District Court sentencing hearing for Jarad Smith, 23, who has pleaded guilty to two counts of dangerous driving causing the deaths of Cathy Pracy, 47, and her partner Gary Kelly, 49.

The court heard Smith most likely had a blood-alcohol content of 0.201 (four times the legal limit for an open licence holder) when he mounted the footpath on Victoria Road, Rozelle and hit Mr Kelly and Ms Pracy about 11am on December 14 last year.

Ms Pracy, an IT professional, died at the scene while Mr Kelly, a high-end mechanic, was taken to hospital in a serious condition and died on New Year’s Eve.

Ms Miller told the court on the morning of her sister’s death she had gone Christmas shopping with her mother and daughter.

“I sent Cathy a photo of mum and myself being silly … unbeknownst to us Cathy at this time had already been killed,” she said.

Ms Miller said a few hours later when she had returned home her son Glenn arrived with a police officer.

“Glenn’s face was one of sheer horror he said, “Mum I need you to sit down.”

Ms Miller said her son told her Ms Pracy had been killed and it was the “stupidity of a drunk driver,” that was to blame.

The families of the victim and the accused wept and Smith bowed his head, his jaw clenched with emotion, as Ms Miller described the heartache of then going to the home of her parents, Erica and John Binder, to tell them what happened.

“It was the most horrible thing I have ever had to do, I will never forget their faces of disbelief and lifelessness,” she said.

“They were that bad I thought mum could quiet possibly have a heart attack or another stroke.” Ms Miller’s son, Glenn, read out a statement on behalf of his Nanna and Opa about the loss of their, “special, kind and always happy little girl”.

“This young man killed our daughter and we will never forgive him,” it said.

A report prepared by a pathologist stated Smith’s blood alcohol level at the time of the crash would have caused, “very substantial impairment of his driving ability.”

He also had traces of MDMA and cocaine in his system.

His lawyer said Smith’s car had been confiscated after the crash and he has not driven since.

Smith spent a month and 24 days in custody after the accident before being released on bail.

The professional Muay Thai fighter had his bail condition varied on March 31 so he could enter licensed premises and compete in bouts.

The sentence hearing continues before Judge Ian McClintock.
