The trial began April 23rd. A verdict is expected before the end of the day.
27-year-old Balfour stands accused of the triple murder after allegedly flying into a blind and jealous rage over a balloon gift for Julia Hudson, Balfour's ex and Jennifer's sister.
Prosecutors say Balfour thought the gift was from Julia's new boyfriend and he snapped.
Balfour has pled not guilty to the murders.
