New Charges Filed Against Suspect in Grisly Murder : Crime: Complaint alleges that woman accused of killing and dismembering her husband imprisoned, tried to rob and assaulted another local man.

A Costa Mesa woman accused of murdering and dismembering her common-law husband was charged Friday with imprisoning and attempting to rob another Orange County man.

Omaima Aree Nelson, 23, also known as Omayma Aref Stainbrook, was arrested Dec. 2 in Costa Mesa and charged with the grisly murder of William E. Nelson, 56, with whom she lived.

The new charges accuse Nelson of false imprisonment, attempted robbery and assault with a deadly weapon in connection with an incident in November, 1990, involving a man identified only as Robert Hanson. The complaint filed against Nelson does not list an age or address for Hanson or give any details of the incident.

Nelson’s public defender, Thomas Mooney, said that Hanson lives in Huntington Beach and that Nelson lived with him for several months in 1990 and 1991. However, he said, Nelson denies having tried to imprison, rob or assault Hanson. “I’m very skeptical about these new charges,” Mooney said.

Mooney said that because of the new accusations against Nelson, he delayed her arraignment in Municipal Court in Newport Beach.

Nelson, who is being held without bail, appeared briefly in the courtroom’s holding cell. She was returned to Orange County Jail after Mooney postponed her arraignment until Feb. 21.

Outside the courtroom, Deputy Dist. Atty. Randolph Pawloski told reporters that he could not elaborate on the new charges.

According to the complaint, Nelson “did willfully and unlawfully violate the personal liberty of Robert Hanson, said violation being effected by violence, menace, fraud and deceit.”

The complaint also says that Nelson “did willfully and unlawfully commit an assault upon Robert Hanson with a deadly weapon, to wit: a handgun, and by means of force likely to produce great bodily injury.”

Another charge asserts that Nelson attempted “by means of force and fear . . . to take personal property from the person, possession and immediate presence of Robert Hanson, and said offense was perpetrated in an inhabited dwelling. . . .”

Mooney said the new charges against Nelson were filed so as to make her face a combined trial in the murder of William Nelson and the Hanson incident. Mooney, however, said he will ask the court to sever the charges into two separate cases.

Mooney said he only learned Wednesday that the district attorney’s office planned to file the additional charges. He said that as far as he could determine, Hanson himself never filed any complaint against Nelson.

Huntington Beach Police Lt. Ed McErlain said Friday that a search of police records could not immediately find any case involving Omaima Nelson or Robert Hanson.
