American Lindsay Souvannarath arrives at provincial court in Halifax on March 6, 2015. Nova Scotia's top court has rejected the appeal of her life sentence by an American woman who plotted a Valentine's Day shooting spree at a Halifax mall in 2015. In a written decision released today, the Nova Scotia Court of Appeal says there is nothing to justify Lindsay Souvannarath's appeal of her sentence of life with no chance of parole for 10 years. Writing on behalf of a three-judge panel, Justice Ann Derrick says the sentencing judge was entitled to determine the gravity of the conspiracy around the plot and was required to decide what sentence would protect the public.
