The Grand Prairie ISD superintendent was killed in a motorcycle crash.

Late Monday afternoon, the district confirmed that Dr. Susan Hull was on vacation in Arizona when the wreck happened.

Public Safety Department of Arizona said the crash happened just after 2 p.m. on Sunday, on I-40 near Twin Arrows, Arizona. Hull was rushed to the hospital with critical injuries.

DPS said Hull died on Monday at the hospital. School officials said that she was surrounded by her family.

Burke Hall, president of the GPISD Board of Trustees said:

“This is a significant loss for the entire Grand Prairie ISD community as well as the education community at large,”

“Over the past 12 years, Dr. Hull has made a significant impact on GPISD and helped establish our reputation around the globe. She also made a lasting difference in school children around Texas through her advocacy and creativity. She will be sorely missed.”

DPS said there was no other vehicle involved in the accident on Sunday.

Dr. Hull was an avid motorcycle rider who previously posted photos on her Facebook page of rides in West Texas.

Dr. Hull’s funeral arrangements are pending.
