According to the pal, "Lauri does not know what to say because what Josh did was so disturbing that there is really nothing she can say right now."

"Her friends are trying to console her and be there for her but she is just so ashamed of what is going on with Josh," the source told RadarOnline.com.

"They used to be so close and he has just turned into a complete monster!"

As RadarOnline.com previously reported, Peterson's son is currently being held behind bars on attempted murder charges after he was chased and arrested by police in Santa Ana, Calif., on Monday.

Although he was scheduled to be arraigned today, the hearing was postponed until Thursday afternoon after he refused to leave is cell.
