HOUMA, La. (AP) — A man who police say confessed to slaying 23 men in south Louisiana during a serial-killing spree that spanned several years is expected to plead guilty today to eight counts of first-degree murder, prosecutors said.

Ronald Dominique, 44, of Bayou Blue, was arrested in December 2006 at a homeless shelter in Houma. He allegedly confessed to raping nearly two dozen men and then strangling or suffocating them.

In exchange for the plea, prosecutors said they will not seek the death penalty in connection with those eight cases.
