TACOMA, Wash. -

Pierce County prosecutors have accused a Puyallup man of supplying the marijuana extract they say his 16-year-old daughter used to make brownies she later gave to classmates.

Several students fell ill after eating the treats Tuesday and told a high school nurse about them.

Both father and daughter have pleaded not guilty to criminal counts.

The News Tribune reports that 45-year-old Michael Miller is charged with unlawfully manufacturing a controlled substance and delivering it to a person under 18. His bail was set Wednesday at $35,000.

His 16-year-old daughter is charged as a juvenile with three counts of unlawful delivery of a controlled substance.

The newspaper says deputies began investigating Miller after Emerald Ridge High School officials reported that several students fell ill after eating the baked goods.

Court records show Miller told deputies he had a medical-marijuana authorization card, but was unable to find it.
