York Regional Police have charged a new suspect in connection with the death of a woman in a house fire in Vaughan last week.

Police were called to the area of Parktree Drive and Lucena Crescent on Sept. 23 to assist Vaughan Fire and Rescue Services battling a blaze.

Officers arrived to locate a woman inside the home unresponsive. She was transported to hospital, where she was pronounced dead. A subsequent autopsy determined the cause of her death was stab wounds.

Police later identified her as 64-year-old Naheed Askaryar.

On Tuesday, police said they arrested and charged a 71-year-old man with first-degree murder and arson endangering life.

However, due to new information from the community, police said investigators uncovered additional evidence, resulting in the charges against the 71-year-old being withdrawn.

Also, the new evidence led to the arrest of a new suspect, identified as 43-year-old Ahmad Shekeb Askarzada, police said.

Askarzada has been charged with first-degree murder and arson endangering life.

Police continue to ask anyone with information to contact the homicide unit at 1-866-876-5423 ext. 7865 or Crime Stoppers anonymously at 1-800-222-TIPS.
