The Oct. 21 traffic stop that may end up costing a Riviera Beach K-9 cop his freedom started like many others.

From his squad car moments after leaving a security detail at a Barack Obama rally, Officer Maurice Morris witnessed a motorist go through a busy Blue Heron intersection at a red light and nearly hit another car.

He pulled the woman over, according to court records.

In time, dispatch told him her driver’s license was suspended. A backup officer arrived.

What comes next, however, had Morris, 43, indicted and charged with bribery, fraud and sexual assault. He’s out on $25,000 bond and the PD placed him on administrative leave with pay.

Morris is accused of, among other things, using his power as a policeman to have sex with the woman. She’s a Haitian immigrant whose identity is being withheld because of the nature of the charges.

“To echo the words of Bill Clinton, my client didn’t have sex with that woman,” Morris’ attorney, Nicole Sauvola, told Page2Live Tuesday. “He’s a victim of her lies. She says the officer put his police dog in her bathroom then assaulted her. The dog is known to be the most vicious in Riviera Beach. Don’t you think the dog would have gotten loose if he heard someone screaming during a rape? We’re trying to find out whether she’s tried to do this before. She’s had a lot of traffic tickets.

“I can’t wait to take this s… to court.”

According to the incident report, Morris wrote the woman two tickets. His backup left the scene as he handed them to her.

Then, according to the woman’s complaint, Morris allegedly yelled at her that he could have her car towed and she could be arrested. When she pleaded with him not to do anything, he told her he’d follow her home, an apartment in a working-class development in West Palm Beach.

What happens next? The alleged victim said the officer offered to “take care of the tickets” if she let him perform oral sex on her.  She let him, even though she described herself as “fearful” and “repulsed.” Then they had what she described as “intercourse, against her will.”

Afterwards, the alleged victim said, Morris ripped up the traffic tickets, took his shepherd out of the bathroom and left.

She called West Palm Beach PD.

According to their report, West Palm CSI noted that the woman didn’t appear to want to press charges at first. She refused to give them the jeans she wore before the alleged assault. She also refused to go to the hospital to undergo rape tests.

But as CSI were leaving, she told them she’d prosecute.

“What the officer did was not right,” she said.

Morris was one of two officers who survived a purge at the city’s K-9 unit in September. The purge came after the cops, based in a small office at the Port of Palm Beach, infected port computers with a virus from porn and dating websites.
