A Calgary couple has been convicted of murdering an elderly man for his truck.

Jason and Tosha Hubler were both charged with first-degree murder in the death of 77-year-old Ray (Rino) Johnson in January 2009.

On Friday, a jury returned a verdict of guilty for both. They were also found guilty of offering an indignity to a body.

Both Tosha, 31, and Jason, 36, had pleaded not guilty to the charges.

Tosha cried in the courtroom as the verdict was read, and Jason stared straight ahead. Both stood up and apologized to Johnson's family.

Tosha's lawyer argued that she participated in the killing under duress, as her husband was allegedly physically and verbally abusive with her.

Jason's lawyer argued that Johnson died after falling down the stairs at their northeast Calgary home when he came over to look at some tools for sale.

'It's just so difficult'

The jury consisted of three men and nine women. Their deliberations lasted eight hours over a period of two days.

About 20 family members decked out in shirts emblazoned with pictures of Johnson hugged and cried after the verdict was read.

The victim's grandson, Tracy Johnson, stood with his family outside court and addressed the media.

"It's hard to think that we could accept those [apologies] now," he said. "Maybe over time. Time does heal, and perhaps we can accept their apology, but it's just so difficult. It's just so difficult, the pain and suffering that this has brought us."

Victim stunned, beaten to death

Johnson, a widower and grandfather who liked to look for flea market goods, was found dead in a trunk in a southeast Calgary industrial park on Jan. 31, 2009.

The Hublers had lured him to their house a day earlier, attacked him with a stun gun and beat him to death before dumping the body and making off with his truck.

Tosha's lawyer Allan Fay spoke with his client after court.

"She's very emotional," Fay told the media. "I mean, she said ... [to a detective] she knows she has to take responsibility for her actions. She regrets what she did, and she's now dealing with the consequences of what she did."

First-degree murder carries an automatic life sentence without parole eligibility for 25 years.
