Paz Quezada has tried to prepare for this day for more than a decade.

On Friday, the man convicted in March of killing her two sons and wounding four others in a 2010 shooting will finally be sentenced. Friday is also her birthday, and her only wish is one she has held onto since the night of the attack: that the man who tore her tight-knit family apart be put away for the rest of his life.

Michael Keetley, a former ice cream truck driver, was convicted of two counts of murder and four counts of attempted murder in the attack. He faces life in prison without parole.
