Investigators found evidence in a murder defendant's pickup that he may have fired almost 30 times during a drunken shooting spree along Interstate 40 in December.

The suspect, an oil-field worker from Texas, admitted after his arrest early Dec. 17 that he had been drinking heavily but he denied doing drugs.

"I've had three tall boys and six shots," Jeremy Doss Hardy said, referring to large cans of beer and alcoholic drinks served in shot glasses.

"More than what I've had in a really long time," Hardy told the Oklahoma Highway Patrol trooper who arrested him after a brief high-speed chase.
