A former D.C. high school track coach faces up to life in prison after pleading guilty Friday to sexually assaulting seven students in 2013 and 2014.

Charles A. Young, 35, who coached at Dunbar High School in Northwest Washington, pleaded guilty to multiple charges, including first-degree sexual abuse, second-degree child sexual abuse and five counts of attempted sexual abuse of a minor.

Young, who has been in the D.C. jail since his November 2014 arrest, stood next to his attorneys as the federal prosecutors outlined the details of the case.

In the first incident, prosecutors said two 15-year-old sophomores met Young in his office to obtain clothes for a basketball practice. Prosecutors said Young took one of the teens into a closet near his office and performed a sex act on him.

In another incident, prosecutors said Young met with a 17-year-old student athlete in his office and tried to perform a sex act on him. Seconds later, someone knocked on Young’s office door and Young told the teen to leave.

The prosecutor then described five incidents in which Young groped teenage boys in his office during meetings with the students about their hygiene, while they were obtaining gym clothes or while discussing their body fat.

As Assistant U.S. Attorney Jason Park recounted the graphic details of each of the incidents, Young at times shook his head. His attorneys, David Benowitz and Brian McDaniel, leaned in and whispered to him. When D.C. Superior Court Judge Robert E. Morin asked Young whether the details of the prosecutor’s accounts were accurate, Young quietly responded, “Yes.”

Young, who will have to register as a child sex offender, is scheduled to be sentenced April 22.

Morin told Young that he would “take into consideration” that Young accepted a plea deal and avoided trial, which was scheduled for later this month. At the trial, Young’s victims would have had to testify publicly.

After the hearing, Young’s wife declined to comment as she left the courtroom. Young’s attorneys also declined to comment.
