A 44-year-old former teacher's aide at an elementary school in New Jersey was read dozens of new charges during a court appearance Monday, including manufacturing child pornography and aggravated sexual assault, according to prosecutors.

Shaun Stebbins appeared in court virtually as authorities outlined the new allegations, which stem from an investigation that began in the spring.

Police have since identified additional alleged victims, including children as young as 3 and 4 years old.
