PHILADELPHIA (CBS) — A 26-year-old Philadelphia man today pleaded guilty to the horrific sex abuse of two small children.

Defendant Steven Mazer has admitted sexually assaulting the two-year-old son and the three-year-old daughter of a friend, babysitting the children while their mother was out of town for a few days.

Prosecutor Vineet Gauri told the court that Mazer enticed and coerced the little victims “to engage in sexually explicit conduct for the purpose of producing visual depiction of such conduct.”

Gauri says Mazer videotaped his acts of sexual assault.

Mazer, who has been in custody since his arrest last September (see related story), is scheduled to be sentenced in October.
