Maricopa Unified School District emailed Butterfield Elementary parents July 25 informing them the Maricopa Police Department inadvertently left narcotics at the elementary school after a July 3 K-9 unit exercise.

Superintendent Tracey Lopeman released a follow-up statement:

“Maricopa Police officers informed an overnight security guard late Wednesday night that there was a concern regarding a training exercise that took place on July 3.  Thursday morning, the security guard alerted District officials who contacted the Police Department. The District immediately began working with the Maricopa Police Department to conduct a search. We asked students and staff to shelter in place. After interviewing teachers, officers determined a search was not necessary.

Our relationship with the Maricopa Police Department is important and the District will continue its partnership with all City agencies. However, this incident necessitates a reevaluation of our agreement to include modifications that ensure human error never puts any of our students or staff at risk.

Student and staff safety is always our first priority. We are very grateful that the students were never exposed to the package.”

“I can’t get into how it happened because the K-9 officer is currently under investigation,” MPD spokesman Ricardo Alvarado said. “From a department standpoint, we are going to evaluate our policies and procedures to make sure that they are up to standards with other agencies that have K-9 programs.”

Alvarado said MPD will not be training in any public locations for the time being.

“Any building or facility that the public may have access to, we’re going to suspend that until we have an opportunity to look at our policies and procedures,” Alvarado said.
