After two days of closing arguments, the jury began deliberations Friday in the murder trial of a disbarred Chappaqua lawyer accused of killing his wife.

The defense claims Carlos Perez Olivo and his wife, Peggy Perez Olivo, were ambushed by a masked gunman on Route 100 in Millwood in November 2006. They say a suspect shot the woman in the head and Perez Olivo in the abdomen.

The prosecution, however, insists it was Perez Olivo who murdered his wife to get hold of $900,000 in life insurance funds.

?The people can't prove beyond a reasonable doubt that my client had anything more to do with this,? says Perez Olivo?s attorney, Christopher McClure. ?He was a victim.?

The jury deliberation, which started at around 3:30 p.m., could last until 8:30 p.m. If the jurors do not return a verdict Friday night, they will continue deliberating Saturday.

Perez Olivo is facing 25 years to life behind bars if convicted of second-degree murder.
