Because of Pell's interest in Manson, there was speculation that the killings had ideological overtones, as did the murders for which Manson was convicted, but robbery was the most likely reason for the break-in, Reynolds said. Pell has dozens of prior convictions for shoplifting, burglary and robbery, dating back to his teens.

One child survived the attack, a daughter, Theresa, 9. Pell overlooked the girl, who was in her bed asleep and hidden by her toys. Because of this, she became known as the "Sleeping Doll."

Like Charles Manson, the criminal he admired, Pell exuded a dark charisma and attracted a group of devoted and fanatical followers, whom he called his "Family"-a term borrowed from the Manson clan-and over whom he exercised absolute control. At the time of the Croyton murders this group included Newberg and three women, all living together in a shabby house in Seaside, north of Monterey, Calif. They are Rebecca Sheffield, 26, Linda Whitfield, 20, and Samantha McCoy, 19. Whitfield is the daughter of Lyman Whitfield, president and CEO of Santa Clara Bank and Trust, headquartered in Cupertino, the fourth largest banking chain in the state.

The women were not charged in the deaths of the Croytons or Newberg but were convicted of multiple counts of larceny, trespass, fraud and receiving stolen property. Whitfield was also convicted of hampering an investigation, perjury and destroying evidence. As part of a plea bargain, Sheffield and McCoy were sentenced to three years in prison, Whitfield to four and a half.

Pell's behavior at trial also echoed Charles Manson's. He would sit motionless at the defense table and stare at jurors and witnesses in apparent attempts to intimidate them. There were reports that he believed he had psychic powers. The defendant was removed once from the courtroom after a witness broke down under his gaze.

The jury begins sentencing deliberations tomorrow. Pell could get the death penalty.
