"Sole carer" dad charged with manslaughter in death of 3-year-old daughter (Petrie, Australia)

I assumed that by "sole carer" they mean that dad MATTHEW WILLIAMSON was custodial.

So who made that fatal decision? How did this come about? What happened to this little girl's mother? Of course, there is not a word of explanation. There seldom is.

A FATHER who had his daughter's name tattooed on his arm and called her his little girl has been charged over the three-year-old's death.

Matthew Williamson is due to appear in court today on charges of child cruelty and manslaughter of Kyhesha-Lee Joughin.

The 28-year-old, who was the sole carer of the toddler when she died in their Petrie unit in March, was interviewed by detectives for five hours yesterday before being arrested.

The father spent the night at Brisbane Watchhouse and is due to appear at Brisbane Magistrates Court this morning.

Police first interviewed Williamson in late March.

The mystery surrounding her death plagued her family, who created a memorial page and spoke to The Courier-Mail about their beautiful girl.

"She was a very bubbly child . . . no matter what, she was always smiling," her uncle Jarrod Williamson said in April.

Police interviewed a 44-year-old Grafton man soon after the toddler's death and he was arrested on traffic charges. He has not been charged in relation to Kyhesha-Lee’s death.
