Stefanie Rengel’s mother bit her lip and took deep breaths as she faced the courtroom yesterday, but the tears kept coming.

In an emotional victim impact statement, Patricia Hung said she is constantly afraid of spiralling into depression and cannot find peace since her 14-year-old daughter was stabbed to death on New Year’s Day 2008.

Rengel’s relatives struggled to put their feelings into words at the sentencing hearing for the 17-year-old girl convicted of first-degree murder in the slaying.

Hung looked directly at the girl, known only as M.T., as she described the rage she battled every day.

“I want inner peace, which is believed to come from forgiveness, but I am unable to forgive someone who has shown no remorse,” she said.

The Crown successfully argued that M.T., driven by jealousy, had used sexual blackmail against her boyfriend to push him into killing Rengel. The Crown is seeking an adult sentence for M.T.

Rengel’s father was unable to read his statement. Instead, he sobbed with his hand held up to his eyes as his best friend read out what he had written.

“Nobody knows the anger and hatred I have for the people who took Stefanie away from our family,” he wrote. “Our lives are changed forever; birthdays, Christmas and New Year’s will never be the same.”

The proceedings resume today.
