Pang said Thursday that blood found on the base of the heavy metal ornament, believed by police to be the murder weapon, ''possibly'' belonged to the deceased.

But he said Friday that DNA and blood from both Nancy Kissel and her husband, Robert Kissel, could be found on the heads of the figurines that were once attached to that base.

Nancy Kissel, 41, is accused of serving her husband a pink milkshake laced with sedatives, which left him unconscious at the foot of their bed before she beat him to death with a heavy metal ornament on November 2, 2003.

The accused told a doctor and the police at the time that her drunken husband had assaulted her after she refused him sex, and then disappeared. She denies the charge and is out on bail.

The banker's decomposing body, wrapped up in a carpet and emitting a foul smell was found in a storeroom in the Parkview residential complex in the early hours of November 7.

Pang explained Friday that he marked out the alleged murder scene from the patches of deep-red staining from which he took samples for his blood and DNA analyses.

He identified stains from a patch of carpet between the foot of the bed and chest of drawers, the chest of drawers, and rim of the wardrobe in the master bedroom, the alleged murder scene, as consisting of blood and DNA that ``possibly'' came from the deceased.

But he could find no traces of blood or DNA from the stain on the wall behind the headboard of the bed.

Items which were found sealed in boxes and visibly soaked with a deep-red element were also taken out of their exhibit bags for Pang to show from which areas he took the samples for his tests.

Results from the samples on bed sheets, duvet, towels, pillows and other bed linen showed there was blood, and DNA results showed they ``possibly'' came from the deceased.

The satins on a cushion which were described by a ``blood-stain pattern'' expert, Dr Lun Tze-shan, as showing signs of being the ``impact pattern'' were also confirmed by tests to carry blood and DNA ``possibly'' from the deceased.
