Kiesha’s mother, Kristi, told police she tucked her daughter into bed about 9.30pm (AEST) on Saturday.
She was reported missing the next morning.
Police say it’s believed that Kiesha has not been seen by anyone other than her parents for three weeks.
The Daily Telegraph has been told that Kiesha, who is in kindergarten, attended only five days at Mt Druitt Primary School this year.
The Education Department declined to comment but police confirmed they had spoken to a number of government agencies about Kiesha’s absences from school and other welfare issues.
Kiesha was reported missing about 10am on Sunday when her mother Christie Abrahams noticed she was not in her bedroom in the family’s unit in Hebersham, in western Sydney.
Ms Abrahams told police she last saw Kiesha about 9.30pm on Saturday when she put her to bed. The family said the unit’s front door was ajar. There were also no signs of forced entry.
However, family and friends have told police they can’t remember seeing Kiesha for about three weeks – about the time her half-brother Levi was born.
Kiesha’s biological father, who lives nearby, has also been spoken to by police and has been ruled out as having had any involvement in her disappearance.
About 100 police, sniffer dogs, and SES volunteers searched bushland around the area yesterday.
Police said children’s clothing found in bushland about 5km from the unit just before 2pm were not Kiesha’s.
Last night another 90 SES volunteers were brought in to help detectives canvass the streets surrounding the missing girl’s home.
It is very likely there are wellfare issues, and the child was let down by children services.
Is that really an abduction case, doesn’t look like it. In most such cases there are family members involved.
