Justin Ouimet

RENO, Nev. (AP) - A 26-year-old man has been sentenced to life in prison without the possibility of parole for killing his estranged wife's son and grandmother in Sparks.

Washoe County District Judge Janet Berry on Friday also sentenced Justin Ouimet (we-MAY') to an additional 61 years for the September 2010 murders.

Ouimet told investigators he was filled with rage about his pending divorce and went to his estranged wife's home determined to murder whoever was there.

He stabbed his wife's 2-year-old son, Connor Lawrence, and 62-year-old grandmother, Lana Stone, then started a small fire inside the house and left. Crews quickly put out the blaze.

His wife, Danielle Lawrence, was at work at the time.

Ouimet earlier pleaded guilty to first-degree murder, assault with a deadly weapon and first-degree arson.
