Murdered Wife's Sis -- 'How Could You Do That?'

Bruce Beresford-Redman just got an earful from his murdered wife's sister in the hallway of court.  Monica Burgos Beresford-Redman's sister, Jeane Burgos, screamed at him, "How could you do that to my sister?"  Bruce looked away and shook his head.

Carla Burgos then screamed out, "Divine justice is gonna get you!"

Bruce and his father walked away, and Carla screamed, "Run away!  Run away!"

Bruce was in court to try to convince the judge to validate his murdered wife's 2008 will, which names Bruce as the executor and gives Bruce's parents an interest in a house Monica owned.  The remainder of the property would go to Bruce.

But here's the problem: There are no witnesses to validate Monica signed the doc.  Bruce says he signed a day before Monica did, but didn't witness her John Hancock.

Bruce did say he believes the nanny did witness Monica signing, but claims she doesn't want to cooperate with him now.  The nanny is saying she knows nothing about Monica signing a 2008 will.

Monica's sisters are challenging the validity of the 2008 will.

The hearing just ended and the judge has not yet ruled on the validity of the will.
