One parent of a first grader told WIS that she didn't fault the staff, but the process.

The district released a statement saying, "The safety of our students is our top priority, and unfortunately district procedures were not followed."

A spokesperson for the child's family told WIS that the teacher did a head-count before students got on the bus, but not after.  They also said the student in question was separated when he was permitted to get a drink.  WIS reported the child was alone for more than an hour and left the park for a time.  He reentered to find a security guard.  The family spokesperson said he was picked up by his father that evening.
