That charge was later upgraded to second-degree murder, but as of Friday that has been changed to first-degree murder.

Tsenga and three other men are accused of fatally shooting Swan in his home on Moodie Drive in southwest Ottawa in the morning of Feb. 22, 2010.

Kristopher Allan McLellan, 20; Dylon Tyrone Barnett, 19; and Kyle Mullen, 19, are also facing first-degree murder charges in relation to the killing.
