The son of a Mississauga woman whose body was found in April has been charged with first-degree murder in connection with her death, police said Wednesday.

Police said Eric Lu, 25 is the son of the victim, Ming-Chien (Teresa) Hsin.

The 59-year-old woman's body was found inside a black BMW with "obvious signs of trauma" in the Robert Speck Parkway and Hurontario Street area on April 10, according to police.

Lu is the third man to be arrested in connection with the murder of Hsin.

On Monday, Peel police arrested 21-year-old Mark Dookhram and charged him with first-degree murder. A day later, they charged Justine Ordonio, 25, with first-degree murder. 

Lu is scheduled to appear at the Ontario Court of Justice in Brampton on Thursday for a bail hearing.

Hsin, who was the owner of a chain of spas, had survived a stabbing in November 2014 outside of her townhouse. Police say they are still investigating and can't confirm if the two attacks are connected.
