The 21-year-old son of a wealthy businesswoman and a 16-year-old were charged with murder today after the older man's mother was stabbed to death.
They are due to appear in court this afternoon.
Assia Shahzad, 40, suffered multiple wounds during the bloodbath at the £600,000, six-bedroom family home.
Neighbours and family friends said that she was estranged from her husband.
Police were holding her son Usman, 21, and a 16-year-old.
The mother of three, who lived with her sons in Aylesbury, Buckinghamshire, had been separated from her husband, Rashad, 45, for several years.
She was taken to Stoke Mandeville hospital on Saturday night after a relative raised the alarm and died shortly afterwards, at about 8pm.
The 16-year-old was also hurt during the incident and was treated for minor injuries at the same hospital.
A friend said: 'Her husband does not live at the house. We have been told that Mrs Shahzad had been seeing other men.'
Another added: 'Assia was a strong-minded, independent, modern woman.' Police said they were treating the horrific incident as 'domestic-related' rather than an honour killing.
A Mitsubishi Land Cruiser remained on the driveway of the house behind wrought-iron gates yesterday.

A family member said her father, Mohammed Nawaz, was inconsolable over the loss of his daughter.
'He is screaming and crying. He is absolutely distraught.'
Muslims arriving at the mosque at the end of Mrs Shahzad's road for prayers spoke of their shock yesterday.
Raj Khan, a Buckinghamshire county councillor who grew up with her, said: 'We lived on the same street, went to school together and we were in the same business together.
'We have a good friendship through our fathers, so there's a long history between us.
'I am devastated. I only saw her yesterday.
'It seems like a total nightmare. She seemed OK - she was her normal self and was talking about going for some food.
'It's a devastating time, not only for her family but for the community. She was a very community-spirited lady.
'She helped where she could, particularly with Asian women's issues by filling in their forms and advising them.
He said that the dead woman's parents were ' absolutely devastated'.
Mr Khan added: 'Her father is not well at all. It's a really bad situation.'
A man who claimed to be Mrs Shahzad's uncle said: 'She was a good lady, well known in Aylesbury. She loved her three children - she lived for her kids.
'I saw her a couple of days ago. She was quite happy. She didn't have any enemies. We can't understand it.'
Forensic officers remained at the house last night and appeared to be focusing on the upper floor of the property.
A second post mortem examination was being carried out on Mrs Shahzad's body yesterday but police said her injuries were 'consistent with a bladed instrument being used in the attack'.
A spokesman added: 'We have seized a number of items as part of our forensic investigation.'
