Two men were indicted on federal charges for the sexual exploitation of children.

Mark J. Bretz, 27, was named in a four-count indictment handed down by a federal grand jury in Erie. He is a former Erie resident.

Bretz received child pornography and used interstate communications to extort several victims into providing him with sexually explicit or suggestive material, according to information presented to the court.

He faces a maximum total sentence of 26 years in prison, a fine of up to $1,000,000 or both.

Another, two-count indictment named Mark A. Prindle, 24, of Erie.

He received and possessed photos and video that showed minors engaging in sexually explicit conduct, the indictment said.

Prindle faces a maximum sentence of 40 yeas in prison, a fine of up to $500,000 or both.

The cases are part of Project Safe Childhood, which is a nationwide initiative by the U.S. Department of Justice to stop child sexual exploitation and abuse.
