DENVER (AP) - A man on Colorado's death row for killing four people at a Chuck E. Cheese restaurant nearly 19 years ago is asking a federal court to overturn his death sentence.
Attorneys for Nathan Dunlap told a panel of the 10th U.S. Circuit Court of Appeals on Tuesday that Dunlap is mentally ill and that his trial lawyers failed to adequately represent him.
Dunlap was sentenced to death after he was convicted of killing three teenagers and a mother of two at the Aurora restaurant in 1993.
He's one of three men on death row in Colorado, which hasn't executed anyone in 15 years. The death sentences of six other death-row inmates have been thrown out since Dunlap was sentenced.
