An HIV-positive man who worked at a middle school allegedly sexually assaulted more than 40 children, intentionally trying to transfer the virus to five of his victims, officials said Monday.

Carlos Deangelo Bell, a 30-year-old man from Waldorf, Maryland, who worked as a teacher’s aide and track coach, was arrested in July and was believed to have victimized 24 underage children at that point.

Bell is now accused of assaulting 42 juveniles, according to a Monday report from the Charles County State’s Attorney’s Office that released new details discovered during a police investigation over the past few months. Altogether, he now faces 206 counts on various sex abuse charges. He is accused of targeting victims from the ages of 11 to 17.

According to Fox News, he targeted his victims at Maryland’s “Benjamin Stoddert Middle School, at his home and possibly at other locations between May 2015 and June 2017.”

Despite being HIV-positive, he did not use any protection while assaulting his victims, CBS News reports.

He is being charged with “five counts of attempting to transfer the virus,” according to Charles County State’s Attorney Tony Covington.

The Charles County State’s Attorney Office said in a statement that it is “not aware of any alleged victim having tested positive for human immunodeficiency virus.”

The state of Maryland is seeking a life sentence.
