One of the key witnesses in a 2000 high-profile murder trial in Las Vegas faces his sixth drunken driving charge.

Steven Kurt Gratzer appeared in Justice Court Monday on a felony DUI charge. Court records say he was arrested Sunday after a Missoula police officer saw him swerving into oncoming traffic, overcorrect and nearly hit the curb.

A breath test showed Gratzer's blood alcohol level was 0.98. Court records say Gratzer also admitted taking the anti-anxiety medication Xanax, along with a stimulant and two anti-depressants.

Gratzer testified during a trial in which Rick Tabish was charged with murder in the 1998 death of casino tycoon Ted Binion. Gratzer said Tabish offered him money for help in killing Binion.

Tabish was acquitted of murder at a retrial.
