LIVINGSTON, Texas (AP) -

Condemned Texas inmate Carroll Parr says he's OK with capital punishment but doesn't believe he should be on death row and face lethal injection this week.

The 35-year-old Waco drug dealer known on the streets as "Outlaw" is set for lethal injection Tuesday evening in Huntsville for a robbery and fatal shooting following a drug deal 10 years ago.

Parr says he believes in capital punishment but disagrees in how it's carried out.

He says he didn't fatally shoot 18-year-old Joel Dominguez outside a Waco convenience store but won't break his word to people involved in the slaying and identify who he says actually did the shooting.

Witnesses at his trial in 2004, including a man who survived a gunshot wound, said Parr was the gunman.
