COPS STONEWALL NAOMI JUDD GUN DEATH PROBE!

Refusing to release any documents detailing what was found at the scene

CHILLING details and official police reports about Naomi Judd’s gruesome gunshot death are being covered up by Tennessee officials who face mounting pressure — and a shocking lawsuit — from the troubled country queen’s own family to bury the real story about exactly how she died!

The National ENQUIRER has learned the local Williamson County Sheriff’s Department wrapped up the investigation into the songbird’s death weeks ago, but has since stonewalled all requests to find out what happened in her Franklin, Tenn., home when she was killed by a bullet on April 30 — just hours before her induction into the Country Music Hall of Fame.

And to make sure that information stays hidden, the 76-year-old music legend’s husband, Larry Strickland, 76, and daughter Wynonna Judd, 58, slapped the sheriff’s department with a lawsuit on Aug. 1, preventing them from releasing any material related to their investigation — including who pulled the trigger.

However, Naomi’s other daughter, actress Ashley Judd, 54, apparently did not join the lawsuit. Legal documents reviewed by The ENQUIRER show Ashley’s name and signature are completely absent.

Sources say that’s particularly significant because Ashley was with her troubled mother just moments before tragedy struck. The local coroner ruled the death a suicide, but the autopsy report has also been kept under wraps!
