Opening arguments began Friday morning at the Westchester County Courthouse in the murder trial of a disbarred Chappaqua lawyer.

Prosecutors say in 2006, Carlos Perez Olivo fired the shot that killed his wife on a dark road, then shot himself in the torso to cover up the crime. He then threw the murder weapon into Echo Lake in Chappaqua, according to prosecutors.

His motive, prosecutors argue, was to collect his wife?s $900,000 life insurance policy. They also say Olivo was having an extramarital affair with another woman for ten of the 30 years he was married.

The prosecutors say they have copious evidence that will lead to the conviction of the disbarred criminal defense attorney of murder. They say the murder weapon, a rare pre- World War II gun, was seen by a witness in the Olivo home before the murder. However, the defense is calling it a prosecution's fairytale.

"The forensic evidence and the ballistic evidence don't support their theory, so they have to manufacture evidence to suit their needs," says Olivo's attorney Christopher McClure."

According to the version of the defense, a car cut Olivo off on state Route 100 as he drove home with his wife from New York City on Nov. 18, 2006. They say the gunman then shot his wife, Peggy Olivo, in the back of the head, shot their client in the abdomen and took off.

The testimony in the case will continue Monday. If convicted, the former Chappaqua lawyer faces 25 years to life in prison.
