Tenn. Cop Killer Got 'Rush' from Killing

A young Frayser man who once told police he got "a rush" from using guns on people, pleaded guilty Thursday to the 2008 shooting death of a Memphis Police lieutenant—his third murder conviction.

Dexter Cox, who was scheduled to go to trial Monday, pleaded guilty to second-degree murder and accepted a 15-year sentence for killing Lt. Ed Vidulich on Jan. 28, 2008, at the officer's home on Shiloh Drive in Frayser.

Cox, now 23, was convicted in earlier trials of killing two other people and is serving consecutive sentences of life in prison, life without parole and 37 years.
