Opening statements were heard Thursday morning in the federal trial of Richard Wilbern, who is charged in the deadly Xerox Federal Credit Union robbery in 2003.

He’s accused of posing as an FBI agent and robbing the bank on the company’s Webster campus 16 years ago. A customer at the bank, Raymond Batzel, was shot and killed during the robbery. Investigators arrested Wilbern in 2016 after linking his DNA from another case to the credit union killing.

Jurors heard from a retired Webster police officer, who was first to respond to the scene and another officer who investigated the case.

There was an emotional testimony from a former employee who described seeing the suspect from her office, dressed in an FBI jacket.

She told jurors she heard two shots and locked the office door and noticed the member lying there with blood behind his head.

“I was wondering what it was going to feel like, if I was going to get shot," the former employee told jurors.

The prosecution says the proof will show that Richard Wilbern was a former disgruntled Xerox employee who had both emotional and financial problems.

However, the defense says police got the wrong man and the case will be based on identification as well as DNA testing that the defense says will leave doubts of reliability.

Testimony in this case continues Friday morning.
