WASHINGTON — A Duke University official has been arrested and charged with offering his adopted 5-year-old son for sex.

Frank Lombard, the school’s associate director of the Center for Health Policy, was arrested after an Internet sting, according to the FBI’s Washington field office and the city’s police department.

According to an affidavit by District of Columbia Police Det. Timothy Palchak, an unnamed informant facing charges in his own child sex case led authorities to Lombard.

Authorities said that Lombard tried to persuade a person – who he did not know was a police officer – to travel to North Carolina to have sex with Lombard’s child.

The detective’s affidavit charges Lombard identified himself online as “perv dad for fun,” and says that in an online chat with the detective, Lombard said he had sexually molested his son, whom he adopted as an infant.

The court papers say Lombard also invited the undercover detective to North Carolina to have sex with the young boy, and even suggested which hotel he should use.

In my book before he burns in Hell, Lombard should die a slow lingering death. Even then it would be enough for what he has done.
