LEE COUNTY, Fla.- Yousil Lopez-Rivera, the man accused of shooting Cape Coral Officer David Wagoner, made an appearance in a Lee County courtroom Monday morning.

Lopez-Rivera pleaded not guilty to that April shooting.

The 20-year-old walked into the courtroom and greeted his new defense attorney.

His arraignment was pushed back from last week because his family was gathering money to pay for a personal attorney.

The prosecutor read the charges to the courtroom: attempted first degree murder with intent to kill a police officer.

Lopez-Rivera did not speak in court.

His lawyer, David Brener, responded to the judge, saying Lopez-Rivera is not guilty.

"Mr. Lopez Rivera is presumed innocent," Brener said. "It is our hope that people will withhold judgement until the trial. it is his right under the constitution not to be presumed guilty."

Lopez Rivera's mother was shaking and holding her hand over her mouth as her son was arraigned.

Lopez-Rivera is set to be back in the courtroom in July.

Officer Wagoner was wearing a bullet proof vest and is expected to fully recover from his injuries.
