The bewildering questions of Lisa McKay-Greening's new reality — of losing her brother in a burst of violence — replay themselves over and over in a painful loop.

"You close your eyes, and you're just there, and you're saying, what could've happened? What could I done differently?" she told CBC News.

Jorden McKay, 27, was shot by an on-duty Royal Newfoundland Constabulary officer Tuesday night in Corner Brook, and died an hour later in hospital.

McKay-Greening said her family has been given no explanation as to how that confrontation went so wrong.
