A man, his ex-partner and their two children have been found dead in Leicestershire.
The body of Aram Abdul Razaq Aziz, 32, was found at Watermead Country Park on Friday night.
Joy Small, 24, was found dead on Saturday at a flat in Mowmacre Hill, Leicester, with son Aubarr Aziz, three, and daughter Chanarra, two.
The deaths of Ms Small and the children at the Jersey Road property are being treated as suspicious.
Police said they were not looking for anyone else in connection with the deaths.
A Leicestershire Police spokesman confirmed there had been previous police involvement with the family.
He said he could not give further details but said discussions had been held with the Independent Police Complaints Commission.
Post-mortem examinations were due to be carried out on Monday.
A spokesperson from the force said: "No causes of death have been established at present, but the deaths of the woman and children are being treated as suspicious.
"Inquiries are at an early stage, but officers are not looking for anyone else at this time."
Neighbours expressed their shock at what had happened.
One neighbour, Jennie Bland, 27, described Ms Small as "such a good woman".
She said: "She was a fantastic mum. She would have died for those children."
Another resident of the flats, who did not want to be named, said she came home on Saturday afternoon to find police cars, an ambulance and a paramedic at the scene.
She described her neighbour as a "lovely woman" who was "really nice".
Floral tributes were being placed outside the Jersey Road flats, along with a pink and blue teddy bear.
One message read: "To a friend, u'll be sadly missed so much, sleep tight."
Others said: "To a beautiful lil girl, Taken so soon, sleep tight", and "To a lovely little boy, taken so soon, sleep tight."
