Week one of testimony in the re-trial of Bob Ward is officially over.

A gun shot examiner testified on Friday, as well as a DNA specialist.

Ward is charged with shooting and killing his wife Diane Ward in the couple’s Isleworth mansion in 2009.

Prosecutors claim it was out of anger because of a business bankruptcy.

Diane died just days before she was due to give a deposition in bankruptcy proceedings.

Ward is on trial for a second time for the 2009 death of his wife. He was first convicted, and sentenced to 30 years in prison, in 2011.

Last year a judge agreed to a retrial, after finding previous defense attorneys did not properly handle and object to evidence in the case.

The trial will resume Monday morning.
