The Cleveland Police Dispatcher involved in the case of the death of 12-year-old Tamir Rice, who was shot by two Ohio police officers last November, has resigned.

Last Thursday, it was revealed that 911 dispatcher Beth Mandl submitted a letter of resignation in July, after taking an unofficial leave of absence from her job on April 3, and failing to show up to work for months.

"I have enjoyed working here and I will miss you all," wrote Mandl in a two-sentence resignation letter to the department dated July 16, according to Cleveland.com.

Mandl issued the letter just days after the department warned her to either provide a "satisfactory explanation" for her long absence or be considered resigned.

Mandl noted that her job was stressful and spoke about quitting before she abandoned the post, according to a department letter. She was not paid during her absence.

Mandl was criticized for her role in the police shooting of Rice, who was shot in the Cudell Recreation Center when police mistook his pellet gun for a real firearm, CNN reports.

Surveillance of the shooting shows that Tamir was walking around and waving a pellet gun in a park outside the recreation center. A man then called 911 to report someone pointing a gun at other people that he believed was "probably fake."

Although the caller stated several times that the weapon was likely a toy, Mandl did not transmit that information to the responding officers. As a result, the officers believed they were looking for an adult black male on a "gun run," Deputy Chief Ed Tomba said, according to NBC News.

The surveillance also revealed that rookie cop Timothy Loehmann fatally shot the boy two seconds after arriving on the scene. Rice was then left lying in the grass bleeding to death for four minutes, until a detective and FBI agent arrived.

Rice died the following day at a hospital.

In a statement, Steve Loomis, president of the Cleveland Police Patrolmen's Association, described Mandl as "outstanding."

"While Beth loved being a dispatcher, she was tired of rotating schedules and mandatory overtime dominating her life. She is an outstanding and caring dispatcher," he said, according to USA Today.
