Woman pleads no contest for murder

An Oakland woman who lured her illicit lover to his execution-style shooting death at the request of her jealous gangster husband pleaded no contest today to second-degree murder.

Aminah "Nay-Nay" Dorsey-Colbert, 30, who was arrested in January 2003, will face a state prison term of 15 years to life when she's sentenced by Alameda County Superior Court Judge C. Don Clay on Aug. 22.

Dorsey-Colbert, who's married to Gregory Colbert Jr., the reputed leader of the "Nut Cases" gang, was charged with murder with the special circumstance of lying in wait in connection with the slaying of youth basketball coach Joseph Mabrey, 36, at the hands of her brother-in-law, Demarcus Ralls, in the 3200 block of Storer Avenue in the Oakland hills on Oct. 24, 2002.

Deputy District Attorney Michael Nieto, who has prosecuted many members of the "Nut Cases" gang, which terrorized Oakland residents in late 2002 and early 2003 by committing numerous murders and robberies, declined to say why he allowed Dorsey-Colbert to plead to the lesser charge.

According to Nieto, Gregory Colbert Jr., 28, whose father, Gregory Colbert Sr., is serving a life sentence for a series of crimes he committed in the East Bay, ordered the hit after he learned Mabrey was having an affair with his wife while he was in prison.

Nieto said Gregory Colbert Jr. hatched an elaborate plot in which Demarcus Ralls posed as Dorsey-Colbert's brother and she pretended that she was having an argument with her husband.

Nieto said Dorsey-Colbert made a "damsel in distress" call to Mabrey in which she said she was in trouble and needed his help at a secluded spot in the Oakland hills.

The prosecutor said when Mabrey arrived at the secluded area, Ralls asked him for a light for a cigarette and then shot Mabrey when he wasn't looking.

Nieto said Gregory Colbert Jr. watched the shooting incident from a nearby van because he wanted to make sure the murder was carried out.

Nieto said Gregory Colbert Jr. ordered his wife to lure Mabrey to his death as a way for her "to redeem herself" for having an affair with Mabrey.

Ralls, 24, was convicted in 2006 of three counts of first-degree murder, including the murder of Mabrey, 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 that was committed while he was a juvenile.

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.

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.

Deonte "Oink" Donald, 22, another "Nut Cases" member, is scheduled to be sentenced Friday for his recent conviction for four counts of murder and other charges.
