Nancy Kerrigan's brother is on trial for killing their father, Daniel Kerrigan, and the jury deliberated for 4 1/2 hours on Monday but went home without a verdict.

The prosecutor told jurors Mark Kerrigan, 46, was an "angry, mean, nasty, drunk son" who killed his father on January 24, 2010.  He is being tried for manslaughter in the death of his father after he passed away during a fight the two were apparently having.  His attorney said their 70-year-old father's longstanding heart disease was to blame for his death.

Nancy has been in the courtroom every day of the week long trial and has been comforting her mother throughout the proceedings. Both Nancy and her mother, Brenda Kerrigan, support her brother, and her mother even testified on his behalf.
