Deonte "Oink" Donald, 22, was convicted March 27 of four counts of first-degree murder, one count each of kidnapping and making criminal threats and multiple counts of robbery and attempted robbery.
He also was convicted of two special circumstance clauses that resulted in the two life in prison terms when he was sentenced by Alameda County Superior Court Judge Allen Hymer: committing a murder during a robbery and multiple murder.
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.
Donald's sentencing means that six of the eight Nut Cases defendants charged in 2003 have had their cases resolved. Most of the defendants have been sentenced to life terms.
On Thursday, 30 year-old Aminah "Nay-Nay" Dorsey-Colbert pleaded no contest to second-degree murder for 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 prosecutor Michael Nieto, 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.
The shooting was carried out by another Nut Cases member, DeMarcus Ralls, 24, who's serving a life term for participating in five murders, but Dorsey-Colbert was charged because she helped set up the incident.
Dorsey-Colbert is scheduled to be sentenced on Aug. 22 and is expected to receive a term of 15 years to life in state prison.
Jury selection for the last remaining defendant, Leon "Twan" Wiley, 29, is scheduled to begin Monday. He's charged with three counts of murder.
Prosecutors believe that Gregory Colbert Jr., 28, was the leader of the Nut Cases gang but he wasn't charged with the other defendants in the case and he was charged separately.
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 2004.
In a May 2 interview with a probation officer, Donald said he realizes that he was "a follower" during the Nut Cases crime spree and he doesn't want to associate with fellow gang members while he's in prison
