The parking lot of Word of Life Christian Center sits empty Friday afternoon, but in cyberspace a blog tied to the church is on fire.

Members have learned of a federal investigation targeting their former Youth Pastor William David Webb.

According to an indictment filed on December 31st, Webb is charged with transporting a person under the age of 18 across state lines with intent to engage in sexual activity.

According to the indictment Webb and the underaged church member were in Oklahoma from March 31st 2004 to April 3rd where the sexual act allegedly took place.

A former church member who asked not to be identified tells CBS 42 that rumors of the incident came to light in 2007 and that's when Webb at the urging of his father Reverend Scott Webb left the church.

With the church office closed, we tracked Reverend Scott Webb down at his Trussville home. But we were only able to get as close as the intercom.

Scott Webb wouldn't confirm why his son left the church, and instead referred CBS 42 to attorney Tommy Spina.

Spina says he has not reviewed the evidence in the case, but that the Webb family stands behind David who will soon return to Alabama to answer the charges.

Says Spina,  "I am aware that he is willing to waive extradition and come back to Alabama to face these charges as soon as he possibly gets here. He's looking forward to his day in court."

A federal judge has set David Webb's Bond at $250,000.
