The second week of Josh Duggar's child pornography trial began on Monday and a new witness made a stunning claim. 

A close family friend, Bobye Holt, took the stand for the prosecution and claimed Josh confessed to molesting multiple young girls during a conversation back in 2003, according to Fox 24 News. 

Bobye and Jim Holt's eldest daughter was Josh's girlfriend in November 2002, when they were 14 years old, so they interacted with the Duggar family regularly.

Bobye alleged that Josh told her a young female minor, 5 years old, sat in his lap during Bible time and he touched her inappropriately. She also alleged he touched three other young female victims while they were sleeping on a different occasion, The Sun reported. 

Bobye then claimed Jim Bob said to her that the relationship between their children had to end and Josh later entered a "troubled youth" treatment facility. 

She later confirmed during cross-examination that she has no knowledge of Josh's alleged 2019 child pornography activities.
