3 years after losing his daughter in the Oatlands crash, Bob Sakr has died aged 53.

The father of Oatlands crash victim Veronique Sakr has passed away following less than a year of battling cancer.

Bob Sakr, 53, died on Saturday, Danny Abdallah, the father who also lost children in the crash, confirmed to the Daily Mail Australia.

"This moment is a celebration for Veronique Sakr, celebrating her dad's arrival into heaven," the family told the publication.

Sakr's daughter Veronique, 11, was killed alongside her three cousins Sienna Abdallah, 8, Angelina Abdallah, 12, and Antony Abdallah, 13, on February 1, 2020, when a drunk and drugged driver struck them as they were walking along a footpath to buy ice-creams in the western Sydney suburb of Oatlands.

In a post shared by the children's memorial page The Four Angels, as reported by news.com.au in June, Sakr said that his cancer has become aggressive, and his doctors had informed him that he had weeks left to live.

"I haven't booked my ticket, and I am not in a hurry, but I am preparing for what's to come next," he said.

He thanked "each and every one of you for being part of my life and allowing me to be part of yours".

"I am not one to bid farewell, but instead, I prefer to say, 'See you next time I'm looking at you.'"

On the first anniversary of the children's deaths, the Abdallah and Sakr families launched 'i4give Day', which is held each year in memory of their children and to help others through grief.

Soon after the crash, Leila and Danny Abdallah — the parents of Sienna, Angelina, and Antony — declared that they forgave the driver, Samuel William Davidson. 

In a statement, they spoke of their "heart-wenching pain and sorrow" following the "unimaginable tragedy," but said that they "forgive the driver".

Earlier this year, at an i4give event held in the children's honour, Sakr recalled how he learned to do that too.

"When I heard Leila say she forgave [the driver], that wasn't going through my head," he explained.

"But then I very quickly realised I was only burdening myself."

Davidson, the driver of the ute, pleaded guilty to four counts of manslaughter and charges related to injuries sustained by three other children.

He was initially sentenced to 28 years in prison with a non-parole period of 21 years, however, this was reduced by the NSW Court of Criminal Appeal to 20 years with a non-parole period of 15 years in 2022.
