A fired Baton Rouge police officer accused of making a bogus 911 call and illegally accessing a criminal history database is trying to get his job back.

The former corporal, Christopher M. Robinson, was terminated in April after internal investigators determined he ditched an extra-duty job at a hospital and called 911 anonymously early one morning in December, telling dispatchers there was a fight going on between two adults outside a Baton Rouge home.

In fact, there was nothing happening outside the residence, which housed Robinson’s ex-girlfriend and their young son, a boy whose custody his parents were fighting over in court.

The woman would later tell investigators she awoke to see Robinson, 36, walk up her driveway and shine a light on the temporary license plate of a truck parked there. Within a minute or two, the several responding units were gone, the woman told police, and no officer contacted her before the police left.

Robinson was issued a summons in January on counts of criminal mischief and unauthorized access to records. In May, he agreed to enter a pretrial diversion program and has since been participating in it, said Hillar Moore III, East Baton Rouge Parish’s district attorney.

Robinson was neither jailed nor charged by prosecutors with a crime in the matter.

“This file has been treated as every other case,” Moore said in a statement. “This is a misdemeanor, and the defendant is a first offender.”

Moore said Robinson was evaluated by a psychologist who determined the former police officer “was of little risk for future aberrant behavior.”

Thus far, Robinson has completed every condition required of him as part of the pretrial diversion program, according to Moore and Robinson’s attorney, Carl Babin.

“The gentleman made a mistake,” Babin said. “He’s owned up to it, and he’s being treated very fairly by everyone involved here.”

Robinson is appealing his termination by the Police Department. An appeal hearing before the city’s Municipal Fire and Police Civil Service Board is set for Aug. 20.

Robinson was fired for violating the Police Department’s policies on “truthfulness” and “conduct unbecoming of an officer.”

In an initial interview with internal investigators, Robinson denied placing the 911 call on Dec. 6 about 4:30 a.m., according to police documents.

But when investigators presented him with a recording of the call in a subsequent interview, Robinson admitted to making it from his cellphone.

When asked why he placed the call, Robinson said he did it because he wanted his ex-girlfriend contacted. His son was sick, Robinson told investigators, and he believed visitors at his ex-girlfriend’s house were contributing to his son’s illness.

According to a summary of his interview with investigators documented in a police report, Robinson said he did not try to see the license plate of the truck in his ex-girlfriend’s driveway. In fact, he said, he never exited his vehicle; he only stopped on the road a few blocks away from her address.

The mother of Robinson’s child told investigators she saw him walk up her driveway in his police uniform before shining a light on the truck’s plate, according to the report.

Upon investigating Robinson further, police determined he searched for the criminal history of his ex-girlfriend on three occasions in 2014 when he was not authorized to do so.

He also illegally searched for the history of a different man associated with her, the report says.

The incident leading to Robinson’s firing was one of several disputes between him and his ex-girlfriend over the past two years in which police were involved. Most of the disputes revolved around child visitation and custody issues.

Babin said his client would not comment for this story.
