OAKLAND, Calif. -- A member of Oakland's infamous "Nut Cases" gang that went on a 10-week crime spree that terrorized the city in late 2002 and early 2003 has been convicted of four counts of murder and could be sentenced to death.

Jurors, who deliberated for about a week, also found 22-year-old Deonte Donald guilty of the special circumstance of multiple murder, which means he will face a sentence of life in prison without parole when he returns to Alameda County Superior Court on May 30.

In addition Thursday, jurors convicted Donald of a number of robbery and burglary charges. Four bailiffs guarded Donald as a court clerk took nearly half an hour to read and record all the verdicts against him.

Prosecutor Michael Nieto agreed to dismiss four counts against Donald after jurors said they were deadlocked on those charges.

Donald's conviction means that six of the eight Nut Cases defendants charged in 2003 have had their cases resolved but two still face trial.

The gang members called themselves the "Nut Cases" because authorities said they engaged in their crime spree mainly for thrills. Some members of the group sported tattoos of the Planters "Mr. Peanut" logo.

The gang member whose case got the most publicity was 24-year-old Demarcus Ralls, who was convicted in 2006 of three counts of first-degree murder, one count of second-degree murder, two counts of attempted murder, 17 counts of robbery, one count of kidnapping and one count of shooting into an inhabited dwelling.

In the penalty phase of Ralls' trial, prosecutors introduced evidence, including a taped confession by Ralls, that he was responsible for a fifth murder.

Prosecutors sought the death penalty for Ralls, but jurors recommended life in prison without parole instead. Ralls was sentenced to four life terms plus 141 years.

Prosecutors considered seeking the death penalty against some of the other gang members, but they dropped those plans after they failed to get the death penalty for Ralls.

Last year, 30-year-old Joe Ralls, the half-brother of Demarcus Ralls, who initially had faced the possibility of being sentenced to life in prison without parole, was sentenced to 23 years after he pleaded no contest to two counts of voluntary manslaughter for killing two people.

Jhomari Sutton, 24, a half-brother to both Ralls, pleaded guilty to 10 counts of robbery in January of 2007 and was sentenced to 15 years and four months in state prison.

Previously, Terrance Hegler and Anthony Wilson were convicted and sentenced for several robberies.

Still awaiting trial are the Ralls' sister-in-law, 29-year-old Aminah "Nay-Nay" Dorsey-Colbert, as well as Leon "Twan" Wiley, 29, the only person in the group who isn't a relative. Dorsey-Colbert is charged with murder with the special circumstance of lying wait in connection with the execution-style slaying of her former lover, 36-year-old Joseph Mabrey, in the 3200 block of Storer Avenue in the Oakland hills on Oct. 24, 2002.

According to testimony and lawyers' statements at Demarcus Ralls' trial, Dorsey-Colbert's husband, Gregory Colbert Jr., ordered the hit after he learned that Mabrey was having an affair with his wife while he was in prison.

DeMarcus Ralls carried out the shooting, but Dorsey-Colbert is charged for allegedly helping to set up the incident.

Prosecutors believe that Colbert, 27, was the leader of the Nut Cases gang but he wasn't charged with the other defendants in the case.

On March 23, 2007, Colbert was sentenced to 75 years to life in state prison for murdering another member of the gang, 20-year-old Glen Phason, in June of 2004.
