FLDS Members Mob Former Follower Who Won Custody of Her Children

Video shows FLDS members in traditional prairie dresses surrounding her van.

Tetzner left the group eight years ago and a Mohave County judge awarded her legal custody of her children, ages 8 to 13, last Thursday.

The standoff lasted for hours until law enforcement arrived and intervened. Afterwards, Tetzner drove off with her children.

Many allege that the FLDS church still maintains control of the local governments, which town officials have denied.

Helaman Barlow, a former chief of the marshals that patrol the twin towns, told ABC News' “Nightline” in an exclusive interview that his job was to “protect the church.” He joined the force 20 years ago and said he quickly learned that the marshals work hand-in-glove with FLDS church security, known as “The God Squad,” who keep a close eye on outsiders.

“They have a huge network of cameras in this community,” Barlow said. “They can watch every street.”

He also said that he lived in fear that Warren Jeffs and other church leaders would take his family away if he didn’t do their bidding.

“This community has always been a theocracy,” Barlow said.

In a statement, the attorney for Colorado City town officials denied that the officials are controlled by the church, and with regards to the former chief, Helaman Barlow, the attorney said, "We question his credibility, since he repeatedly lied under oath."

Barlow admits he has perjured himself while defending the church in the past, but insists what he is saying now is true.

But the incident with Tetzner demonstrates how many in the community remain loyal to the church.
