Police Seek Boy's Parents

Police say a 4-year-old boy took rocks of crack cocaine -- worth about $10,000-- out of his backpack and showed them to other kids in his Head Start class. He said it was flour.

But teachers realized it was cocaine and called authorities.

"He took it out and showed the other students this particular substance, and was describing it as flour," Indianapolis police Sgt. Roger Tuchek said.

Officers searched the boy's Indianapolis home and found a small amount of marijuana inside, police said. The boy's parents were not there. There are now warrants for the parents' arrest.

The boy and his sister are in protective custody.

Meanwhile, there's a similar case in Florida.

Police in Miami say it wasn't oregano that a 5-year-old brought to school and sprinkled over a friend's lasagna -- it was marijuana.

A monitor intervened, and the food was confiscated before the other boy had a chance to eat it. Police say it's unclear whether the kindergartner even knew what it was, although they say he tried to hide the bag when a cafeteria monitor approached.

Authorities are investigating the boy's family.
