Officers responded to an "unknown trouble" call shortly before 2 a.m. last Saturday at a condominium complex on Yonge St., just north of Elgin Mills Rd., and discovered the woman's lifeless body.
The dead woman's brother, Jonathan Ross, was arrested at the scene.
The 36-year-old Richmond Hill man is charged with second-degree murder.
Police revealed Friday that the victim is Jeannine Ross, of Thunder Bay.
"The victim was the sister of the accused," police said.
A post-mortem examination has determined Jeannine died from "blunt-force trauma."
Police are asking anyone with information pertaining to this case to call their Homicide Unit at 1-866-876-5423, ext. 7865, or York Crime Stoppers at 1-800-222-TIPS (8477).
