MILWAUKEE (CBS 58) -- An MPS safety worker and youth coach remains behind bars Sunday, August 30, after appearing in court earlier in the day.

Antonious Partee is accused of committing four felonies against middle school students. His cash bond was set at $30,000.

The judge spoke about the severity of the allegations he's facing: grooming children for sexual activity.

And the district attorney hinted there could be more victims.

Partee faces more than 30 years in prison if he's convicted.

In court, commissioner Andrea Bolender said, "With that significant exposure we do know based on evidence-based studies that can increase your likelihood of flight."

Bolender added, "This court has an additional factor to take into consideration and that is the protection and safety of not only these victims, any other victims who may still come forward, but the community as a whole."

The charges against Partee stem from multiple social media exchanges with 14-year-old and 15-year-old boys. He made several sexual advances. He also called the victims repeatedly, sometimes as late as 3 am.

One 14-year-old victim told investigators, "this is actually scary" and worried other adults at his new school would act the same way.

In court Sunday, assistant district attorney Anthony Moore said there could be more victims. "My notes do indicate there are two other children at this point who are coming forward."

Partee previously confessed to investigators, referring to himself "as a bad person multiple times."

He said he had a drinking problem and would get drunk and message the middle schoolers "for sexual advances."

Partee's attorney requested, and was granted, alcohol addiction treatment and mental health treatment.

Antonious Partee only spoke once throughout the hearing. When the court commissioner barred him from any contact with the middle school at which he worked, he said simply, "Yes, ma'am."

As of Sunday night, Partee has not posted his bond and remains in the Milwaukee County jail.

He's scheduled to have his preliminary hearing September 8.
