TORONTO -- A 38-year-old northern Ontario woman found slain in a Richmond Hill condo last weekend was allegedly killed by her younger brother, York regional Police said Friday.

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."
