Callie, a facility dog at Bonfield Elementary School in Pennsylvania's Warwick School District, died after being left in a hot car on June 11.
Police investigated the incident, and the Lancaster County District Attorney's Office determined no criminal charges would be filed, calling it a tragic accident that did not meet the legal standard for a crime.
The school district said an internal personnel process is ongoing and described Callie's death as a devastating loss for the school community.
