A third member of the extended family of Brampton mother Poonam Litt has been charged in connection to her death.

Skinder Punia, Litt's 43-year-old brother-in-law, has been charged with accessory after the fact to murder, Peel Regional Police said Wednesday. He was due to make a morning appearance in court.

Punia's wife, Mandeep Punia, had been charged in April with the second-degree murder of Litt. Litt's father-in-law, 63-year-old Kulwant Singh Litt, was also charged in April with accessory after the fact to murder.

Police revealed on Apr. 22 that human remains found in February on a property in Caledon Village, about a half-hour drive northwest of Brampton, were identified as Poonam Litt.

Police allege that Mandeep Punia killed Litt on Feb. 4, 2009. Litt was 27.

Litt typically walked to her workplace, a dental office a few blocks from her home. But on the morning of Feb. 5, 2009, she never arrived and was reported missing.

Her family later offered a $25,000 reward for information that could lead police to her whereabouts.

Poonam Litt's sister Nicky Dhaliwal attended court on Wednesday along with other family members. She told CBC News she hopes the new charges are another step toward getting justice for her sister.

"I feel like, a little bit of relief because we didn't know for three years what happened to her, where she is," she said.
