Accused murderer Nancy Kissel admitted Thursday she used a heavy metal ornament to kill her husband, banker Robert Kissel.

The accused was subjected to an intense afternoon of questioning on what she had earlier testified was persistent drug-fueled, forceful sexual abuse.

With his first question in cross-examination, Senior Assistant Director of Public Prosecutions Peter Chapman dealt with ``just one little matter that [the accused] might be able to help us with - Do you accept that you killed Robert Kissel?'' he asked.

Kissel replied: ``Yes.''

The prosecutor then asked: ``Do you accept that you used that ornament to inflict those [fatal] injuries?''

She replied: ``Yes.''

The prosecution alleges that Kissel, 41, murdered her husband on November 2, 2003, by serving him a milkshake laced with sedatives that left him unconscious at the foot of their bed before she bludgeoned him to death with the heavy metal ornament.

She has pleaded not guilty and is out on bail.

Kissel testified Wednesday there had been a furious struggle between her and her husband in their bedroom on the night of the killing. After knocking him on the head with the metal ornament while resisting more sexual abuse, she said, the banker charged at her with a baseball bat, repeatedly saying: ``I'm going to kill you, you bitch.''

The victim's decomposing body was found in the early hours of November 7, 2003, wrapped in a rug in a storeroom at the couple's Parkview residential complex.

Earlier Thursday, she was asked by her counsel, Alexander King SC, whether she could remember how the fatal blows to the head of the deceased got there. She sat in the witness box in silence, shaking, and offered no reply.

The prosecutor established during cross-examination with the accused that aside from two occasions in 2003, she had never seen a psychiatrist and had no history of memory loss before the night of the alleged murder.

Chapman returned to Kissel's testimony where she described her life as a fashion and design student in New York, juggling three catering jobs to fund her husband's MBA and cocaine use.

``You were supporting him, you were giving him the money. How much would he spend on the drugs?'' asked Chapman.

Kissel replied: ``It would vary. Sometimes US$100 [HK$780] a day, sometimes more.''

The prosecutor asked: ``So you were giving him US$3,000-US$5,000 a month?''

The accused said: ``There were times he received drugs without payment. I don't know where he got those drugs from. On occasions, friends would give him drugs.''

Chapman asked: ``[US] $2,500?'' ``I don't know,'' she replied.

``US$2,000?'' he asked again.

``I don't know.''

``US$500?''

``I don't know.''

``So how much were you shelling out for Robert's cocaine habit? Give us a figure Mrs Kissel,'' said Chapman.

The accused said she could not, since her financial support went to food, rent and other expenses, but that she was largely paying for the drugs at the beginning of their relationship.

``And while all this was going on, you managed to purchase property in New York,'' said Chapman.

Kissel said she could not remember how the loft apartment in Greenwich Village was paid for.

Chapman asked: ``While he was in Hong Kong, where was he getting his cocaine from?''

Kissel replied: ``I don't know.'' She said she never asked where he got his supplies from and did not know whether he used it on business trips.

``Did you remind him that countries around this area take a pretty dim view of hard drugs?'' asked Chapman.

The accused said she only talked about the health issues.

``He's not much good to you busted in Malaysia on drugs charges, is he?'' asked Chapman.

Kissel agreed.

When they came to Hong Kong, ``did the frequency that he demanded anal sex change in any way?'' asked Chapman.

She said it ``increased tremendously'' towards 2002.

``How often each month would you be having forced anal sex with Robert Kissel?'' he asked. She said she never counted.

``Give us a number Mrs Kissel?'' asked Chapman.

She replied: ``It wasn't about how many times. It was a progression of how we were together. Starting in different positions. The ability to move into those positions. Progression of sexual activity. There were times that he got very frustrated, by my changing, moving into ways he didn't want. It was a period in which things developed into something different. There was force involved.''

When Kissel testified that her husband had never used protection against AIDS and other sexually transmitted diseases, Chapman pointed out that two of her close friends had sexually contracted HIV and died of AIDS, including her maid of honor, Ali Gertz.

He asked if Gertz's fate had ever crossed her mind during the periods of sexual abuse, or when her husband was traveling and suspected of seeing other sexual partners.

She did not believe those factors would make her husband ``high-risk,'' although she had a ``huge awareness of AIDS,'' when her friend was diagnosed

Chapman asked: ``In relation to these activities - cocaine, alcohol-fueled anal sex with you by Robert Kissel. Did you at anytime tell anyone about it?''

``No,'' she replied. ``It was something that was happening gradually in my marriage. Something I took responsibility for, not something you talk about to the girls.''

The prosecutor asked: ``During the more violent episodes - that involved hair being pulled, ribs being broken and pain causing blood - did you ever scream out?''

``Did I scream out? - I may have,'' she replied.

``Did anyone ever hear you over five years?'' he asked. ``I don't know ... a lot of the time, I cried,'' she said.

Chapman asked: ``Have you ever been examined in relation to the results of forceful anal sex over this five-year period?''

``No, it's humiliating,'' she said.

The trial has been adjourned until Monday.
