SLIDELL, LA (WVUE) - A Slidell Police Department detective resigned after an internal investigation found he neglected to investigate cases assigned to him.
According to the Slidell Police Department, Detective Mario Arthur III resigned after an internal investigation found he had been grossly neglecting his investigatory duties and mishandling evidence.
Slidell Police Chief Randy Smith began the investigation in June 2015. At the same time, Arthur was transferred to the patrol division.
According to the police, investigators discovered multiple cases which were not properly investigated by Arthur. Those cases have since been reassigned and properly investigated.
"Our detectives are held to the highest level of standards," Smith said. "This type of negligence is an isolated incident and is completely unacceptable. We want to be transparent with this investigation which is why we asked an outside agency to review our findings."
The allegations against Arthur were sustained by the investigation according to the police. He is charged with several police violations including Neglect of Duty, Unsatisfactory Performance and Insubordination. As a result, he has resigned from the department.
Slidell Police turned over the findings of their investigation to the 22nd Judicial District Attorney's Office and the Louisiana Attorney General's Office. The investigation is ongoing.
