Susan Addis, 69, was discovered with stab wounds at her home in Brighton on Thursday.
It’s unclear how the attack unfolded. Friends said she lived alone, but knew the suspect.
“By the sounds of things there has been some sort of altercation in the house and Sue has suffered some injuries,” an unidentified friend told The Sun.
The suspect, who has not been publicly identified, was charged Friday with murder, according to The Sun.
Addis ran two popular restaurants, Donatello and Pinocchio, that are frequented by celebrities and athletes.
Addis’ family pleaded for privacy, adding they were “in a state of shock” over her killing.
