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.
