Some Cambodians are upset over the sentence given to the former chief jailer of the nation's notorious Khmer Rouge regime that killed nearly 2 million people.

A court found Kaing Guek Eav guilty of crimes against humanity and sentenced him to 19 years in prison.  But some Cambodians feel the penalty was too light.

Eav, who goes by "Duch" (pronounced "Doyk"), was responsible for overseeing the deaths of up to 16,000 people. The brutal regime killed 1.7 million Cambodians from 1975 to 1979 in what became known as Pol Pot's "killing fields."

The former head of the torture center used to extract "confessions," was the first Khmer Rouge leader to be sentenced.

He is also the only one of five leaders on trial to admit his crimes. Duch became a Christian while in hiding in 1993.

Christopher Lapel, a Cambodian-American pastor, helped lead him to Christ. 

"He came to me and he said, 'Pastor Christopher, I'm a sinner and I don't think my brothers and sisters around me can forgive me because my sins are so deep," Lapel said.

Duch has apologized for his crimes. His testimony could convict those who ordered the killings, and bring justice to the victims.
