A troubled teenager and her father found fatally injured at their home both died after suffering stab wounds, detectives said today.
Police released the results of post-mortem examinations two days after Margaret Pierides, 16, and her father Costas, 48, were discovered at their £750,000 house in Sible Hedingham, Essex.
Officers say they are not looking for anyone else in connection with the investigation.
Margaret died after being airlifted to hospital. Mr Pierides, a businessman, was pronounced dead at the scene, police said.
The teenager's friends spoke of the rocky relationship she had endured with her father but said the pair appeared to have "patched things up" recently.
She had returned home a "few months ago" after spending time in a youth hostel in nearby Braintree.
Kika Willings, 18, who went to school in the village with Margaret, said: "When she went back home she was so happy. She was proper sorting her life out.
"She seemed to have patched things up.
"We were best friends. She was so much fun to be around. She was crazy."
Miss Willings's mother, Celestine Adams, 45, described Margaret as a "wild card".
In a tribute written to Margaret's mother, Bernadette, Mrs Adams said: "Bernadette, please take comfort from the fact that Margaret, the last couple of times we saw her, had a glow, a confidence and was looking gorgeous.
"She loved you and her brothers and sisters.
"Margaret was a lovely girl, a wild card - a little troubled but a lovely girl."
