Apparently a 6-year-old got ahold of someone's prescription medication and decided to experiment with her friends.
Arizona's ABC15 reports:
According to Phoenix Fire Department, four elementary school students took "what appears to be heart medication pills" on the school bus Thursday morning.
Phoenix police say a 6-year-old girl took the prescription pills from an adult family member and gave them to four other 6- and 7-year-olds while they were on the way to school.
A staff member at the school became aware of what happened, brought the kids to the nurse's office, and called 911.
