Scott, who faces a maximum sentence of 30 to 60 years in prison, and Murchison, who was sentenced to two life sentences for the murders and at least 75 years for the related offenses, are expected to testify against their remaining co-defendants.
They include:
* Will "Pooh" Hook, 43, a/k/a Keith Epps, whom prosecutors contend masterminded the robbery gone wrong, which ended in the slayings in the hallway of Thal's apartment house, the Piazza's Navona building.
Hook, a bald, hulking figure dressed in a black turtleneck sweater and dark pants, is charged with two counts of second-degree murder and related counts. If convicted, he'd be sentenced to two mandatory life sentences.
* Antonio Wright, 30, one of the accused gunmen who was caught on surveillance tape casing the hallway before the murders, is charged with two counts of first-degree murder and related counts. Yesterday, he caught a break when the District Attorney's Office took the death penalty off the table. He also faces two mandatory life sentences if convicted.
* Edward Daniels, 44, who was seen on tape near Thal's apartment before the murders, is also charged with first-degree murder and related offenses.
* Robert Keith, who'll be 30 Saturday, is charged with burglary and criminal trespass, for allegedly trying to break into Thal's apartment the day of the slayings. Sources said that he was expected to plead guilty today.
The guilty pleas of Murchison and Scott follow that of Katoya Jones, 27, who pleaded guilty last November to third-degree murder and related charges.
Jones, a resident of the same apartment building as Thal, will also testify for the prosecution. She is accused of opening an exterior door to let her co-defendants in the building in exchange for a $50,000 to $60,000 cut of the loot. Police later found $110,000 in cash and more than eight pounds of cocaine in Thal's apartment.
