A jury found Mandeep Punia guilty of the lesser charge of manslaughter in the death of her 27-year-old sister-in-law on Saturday, after acquitting the Brampton woman of second-degree murder.
Punia's husband — Skinder Punia — was also found guilty of acting as an accessory after the fact to manslaughter in the death of Poonam Litt.
Litt was reported missing in February 2009. Her remains were found on a property in Caledon Village, about 25 kilometres northwest of Brampton, three years later.
The young mother worked at a dental office a few blocks from her home and walked there each day. But on the morning of Feb. 5, 2009, she never arrived.
Litt had a young daughter and was pregnant at the time of her death.
Her husband, Manjinder Litt, travelled to India on Jan. 13, 2009, which was the last day he saw her, according to police at the time of the search.
At Punia's first court appearance, police said Litt's husband had never been considered a suspect in her disappearance.
Punia's sentencing date has not yet been set.
