Indictment in Dallas Cold Case

DALLAS (AP) _ Exactly 27 years after a suburban Dallas police officer was shot dead in his patrol car, authorities say they have indicted a man for capital murder.

Dallas County District Attorney Craig Watkins announced Friday that 63-year-old Gary Wayne Pettigrew faces a capital murder charge in the slaying of Farmers Branch Police Officer Lowell Tribble.

Tribble’s case was the oldest unsolved police officer killing in Texas.

The case was reopened in 2007 by the DA’s office and Farmers Branch police.

Pettigrew has a rap sheet dating back to the 1960s, with convictions for driving under the influence, burglary, resisting arrest, drug charges and auto theft. He was arrested Friday morning.

Pettigrew’s attorney says his client proved his innocence with a polygraph exam.
