Before killing himself, a Texas sergeant confessed to child sex assault involving himself and two of his coworkers, police said.
The coworkers have now been arrested and charged in connection to the allegations.
The allegations started a week ago when officials questioned a dispatcher regarding her poor work performance, authorities said.
At a press conference on May 21, Harris County Precinct 1 Constable Alan Rosen said that is when the dispatcher, Christina McKay, blurted out that her co-worker, Sgt. Robert Johnson, was sexually abusing children.
"It's pretty apparent that everybody around this guy had no idea that he was a pedophile. Not his wife. Not his friends. Not his co-workers. Nobody," Rosen said.
At that point, Rosen’s office contacted Houston police and other agencies in the area, including Child Protective Services, and an investigation started, authorities said.
According to investigators, McKay said Johnson, who was married, and Dep. Chonda Williams were having a months-long affair that also involved a minor.
McKay said before one sexual assault, Johnson gave the minor some pills “so she wouldn’t be aware,” police said.
While talking with investigators, McKay also admitted to having an affair with Johnson, authorities said.

It was confirmed McKay made reservations at a hotel in Pearland, Texas, more than 20 times and at least one time, she gave Johnson pills to “sedate the minor children victims” during the sexual assault, investigators said.
Police said one time when Johnson left the hotel, he carried a child out over his shoulder.
On May 19, officers were looking for Johnson and tracked him down and tried to pull him over, authorities said.
A chase began and then a six-hour standoff ensued. During that time, Johnson called police and made a “dying declaration” before taking his own life, officials said.
"Johnson confessed to everything he had done and he implicated two other employees at this office, Christina McKay and Chonda Williams," Rose said.
McKay and Williams were fired, arrested and charged with sexual assault of a child, police said.
They both remain in jail and both their bonds are set at $200,000.
Before joining Harris County Precinct 1, Johnson was fired from the Harris County Sheriff’s Office for an inappropriate relationship with an adult, Rosen said.
However, Rosen said he was trying to give Johnson a second chance and he passed a psychiatric evaluation and background check before being hired.
