Just over a week before his wife's Friday sentencing for shooting at him for his alleged affair, Fort Lauderdale Police Chief Frank Adderley filed for divorce.

Court documents indicate it was a Christmas gift of expensive earrings to another woman that made Eleanor Adderley snap.

Frank Adderley filed for divorce Sept. 23, saying his 18-year marriage to Eleanor Adderley was ``irretrievably broken.'' He requested custody of their 16-year-old son.

Since the July 2008 shooting at their Plantation home, the couple have been ordered to have no contact.

Friday, Eleanor Adderley, 46, is expected to be taken into custody when Broward Circuit Judge Jeffrey Levenson sentences her. She faces nine months in the county jail or up to 30 months in prison for the shooting.

Authorities say Eleanor Adderley used the chief's gun to fire one bullet into the foot of the bed her husband was lying on, and two more rounds outdoors as he ran to a neighbor's house. The chief, 48, was unharmed.

BETRAYED WOMAN

In legal documents arguing for the shortest possible sentence, Eleanor Adderley's attorney, David Bogenschutz, relies on mental-health reports to paint a picture of a betrayed woman who could not emotionally cope with her husband's infidelity and became increasingly depressed, suicidal and socially withdrawn.

``With the kinds of problems and stress she's been going through and was under at the time, her husband, the arresting detective and probation officer all believe that she shouldn't be going to jail,'' Bogenschutz said.

She was diagnosed with multiple sclerosis several years ago.

Neither Frank Adderley nor his divorce lawyer, William L. Gardiner III, could be reached for comment.

Eleanor Adderley's original charge of aggravated assault with a firearm carries a mandatory 20-year term of imprisonment. She pleaded no contest to aggravated assault without a firearm and a charge of using a gun in an occupied building, eliminating the mandatory 20-year sentence.

LEARNED OF AFFAIR

According to court records, Eleanor Adderley discovered her husband's affair in May 2008 when she examined his cellphone records. He admitted to the affair, and when Eleanor Adderley called the ``other woman,'' she also admitted to the relationship.

On the morning of the July shooting, the chief and his wife argued over his Christmas gift to the woman. He told his wife he had given the woman an inexpensive piece of jewelry, but Eleanor Adderley found that it had been a ``quite expensive'' gift -- costing more, in fact, than the gift she had received from her husband.

This revelation, according to the documents, made her feel that her husband continually was dishonest with her and caused her to ``snap.''
