Family battered with metal rod
Katy and Emily were beaten to death by killer
The killer of a family of four used a metal rod to bludgeon them to death, police have revealed.
The four-foot-long murder weapon was left behind by the killer in the fire-blackened house where 34-year-old divorcee Mandy Power, her daughters Katy, 10, and Emily, eight, and her disabled mother 80-year-old Doris Dawson were killed.
It has been taken to a forensic science laboratory to be checked for DNA and fingerprints.
A "Cracker-style" clinical psychologist has been brought in by police to draw up a personality profile of the killer.
Officers from the National Crime Faculty - who have helped in the hunt for the killer of Jill Dando - have also been brought in.
"We have the best possible expertise available to catch the killer," said Det Supt Lloyd-Evans
He described the finding of the rod as "very significant" and disclosed that it was found in the early stages of the investigation, but forensic tests and post-mortem examinations of the four victims had now confirmed that it was the murder weapon.
"We are trying to find out what this implement would normally have been used for and it is possible the killer brought it to Mandy's house.
Wielded by killer
The one-inch diameter rod, with a glass fibre and black plastic covering, was wielded by the killer who repeatedly struck Mrs Power over the head in the frenzied attack at her home in Kelvin Road, Clydach, near Swansea early last Sunday.
The former school cleaner was savagely beaten as she made a vain bid to save the lives of her daughters Katie and Emily who also received severe head injuries.
The killer then started several fires in a bid to destroy evidence before fleeing the semi-detached house.
Police still believe that bisexual Mandy Power's tangled love life holds the key to discovering the motive for the carnage.
She had had relationships with men and a woman since splitting up from her husband Michael two years ago.
Detectives are also tryingto trace a mystery caller who went to the family's home at about 12.45am on Sunday morning.
A neighbour heard the sounds of someone being dropped off outside the house before a diesel-engined car was driven away.
On Thursday, nearly two dozen people visited the house to lay flowers, small teddy bears and messages in remembrance of the family.
They were led by Mandy's older sisters, Julie Evans and Sandra Jones, who made a public appeal for help to find the killer.
At a police news conference the sisters whose family has been torn apart by four murders begged anyone with information to come forward.
Sandra Jones and Julie Evans spoke of the loss of their mother, sister and two young nieces.
"The sense of loss that we felt is indescribable and the whole family has been devastated by what has happened," Mrs Evans said.
"We are all deeply proud of them and loved them all. Mandy was a good and loving mother and we were a close and happy family."
Results of earlier post mortem examinations revealed that all four victims were dead before the killer set alight to the semi-detached house in an attempt to destroy evidence.
Mrs Power had been sexually assaulted before being bludgeoned by the killer.
