Baby Death Murder Inquiry
The family of a baby girl believed to have been murdered have described her as their ``little princess'' who ``always had a smile for everybody''.
The 11-month-old was named by police as Crystal Hall-Hummel, who added that a post-mortem examination has failed to determine her cause of death.
A 26-year-old man who was arrested on suspicion of murder following her death on Saturday has been freed on bail until June 20, Sussex Police said.
Paramedics were called to a property in Nursery Lane, Worthing, West Sussex, just before 10am on Friday and tried to resuscitate the baby after she had stopped breathing.
She was admitted to Worthing Hospital from where she was collected by a specialist team from St Thomas's Hospital in central London.
She was pronounced dead just after 3pm on Saturday and the man, from Worthing, was arrested at St Thomas's on suspicion of murder.
In a statement released through police, the baby's family said: ``Crystal was a happy baby and full of energy. She always had a smile for everybody.
``She loved splashing around in the bath, being cheeky, loved attention and cuddles.
``What has happened has shocked all of us and words can't describe how we all feel. Crystal was a massive part of everyone's life.
``Our love for her is indescribable and we miss her so much. She will live in our hearts forever and will always be our little princess looking down on us from heaven.''
Further tests will now be carried out to determine how Crystal, who lived in Christchurch Road, Worthing, died.
A police cordon remains in place at the property in Nursery Lane and is expected to remain for at least another two days while further forensic examination takes place.
Detective Inspector Carwyn Hughes, who is leading the investigation, said: ``A post-mortem was carried out in London on Monday by a Home Office pathologist and a specialist paediatric pathologist.
``They have given us provisional information with regard to the result, but further extensive tests will need to be carried out to conclude their examination.''
