Sources tell us the D.A. believes there is "insufficient evidence" to prosecute Lindsay.

The Palm Desert Police Department had been investigating the confrontation between Lindsay and former staffer Dawn Holland, but ultimately the D.A. felt the firepower wasn't there.

So Lindsay only has one criminal case in play now.
