For the latest on this story: Husband of Calgary woman killed in gas-and-dash dies in crash on B.C. highway

The husband of a woman killed trying to stop a gas-and-dash in Calgary has died in a crash while driving from Vancouver for the two-year anniversary of her death.

Ahmad Nourani Shallo was travelling to Calgary from his home in Vancouver with his son, Koorosh, and his second wife when they crashed on the Trans-Canada Highway near Golden, B.C., on Thursday.

They were on their way to Calgary for the two-year anniversary of the death of Shallo's first wife, Maryam Rashidi.

"Everyone is shocked. We're all devastated. We can't believe this," family friend Ehsan Hosseini told CBC News.

Rashidi had moved with her husband from Iran only four months before her death, to work as engineers in Calgary's oil and gas industry.

After both were laid off, Rashidi took a job as a gas station attendant at the Centex on 16th Avenue N.W.

​She was only on her fourth shift on June 7, 2015, when she was killed trying to stop a man who attempted to drive away without paying for $113 in fuel. 

Son and new wife survive crash

Last week's crash in B.C. sent Shallo's new wife to hospital, where she underwent surgery for broken bones. She is expected to recover.

Shallo's son, Koorosh, was asleep in the back seat of the car and suffered only minor injuries.

Shallo's parents have flown to Canada from Iran.

Joshua Mitchell, the man who killed Rashidi, was charged with second-degree murder in her death and was convicted of manslaughter in early May 2017.

Rashidi climbed on the hood of the vehicle, a stolen Ford F350, while it was stuck in traffic.

Mitchell tried to jostle her off, but she fell under the vehicle and he drove over her, causing fatal injuries.

He will be sentenced on Aug. 30. 

Shallo moved to Vancouver soon after Rashidi was killed.
