Michigan is joining other states considering laws that require prompt reporting of missing children.
A bill approved Tuesday in the Michigan Senate by a 35-0 vote comes after the acquittal of Casey Anthony in the death of her daughter, Caylee, in Florida. The child was not reported as missing for about a month after her disappearance in 2008.
The Michigan bill would require parents or other caretakers to "immediately" report a missing child. Legally, an individual would have reason to know a child was missing if he or she did not know the child's location or have contact with the child within a 24-hour period.
A child is defined as less than 13 years old. The bill advances to the Michigan House. Many other states have proposed similar laws.
