TONIGHT A CBS 11 I-TEAM EXCLUSIVE, THE SUPERINTENDENT OF ONE OF THE LARGEST AND OLDEST CHATTER SCHOOLS IN DALLAS QUITS, AND IT COMES AN THE I-TEAM OBTAINS HUNDREDS OF PAGES OF CREDIT CARD STATEMENTS IN AN OPEN RECORDS REQUEST. BRIAN NEW HAS THE STORY WITH US WITH THE INVESTIGATION. BRIAN? Reporter: THE SUPERINTENDENT RESIGNED LAST NIGHT JUST FOUR DAYS AFTER THE SCHOOL DISTRICT PROVIDED US WITH THESE FINANCIAL DOCUMENTS. BUT WHAT THE TAXPAYER FUNDED CHARTER SCHOOL HAS NOT PROVIDED US IS AN EXPLANATION FOR THE TENS OF THOUSANDS OF DOLLARS THAT THE SCHOOL’S TOP OFFICIALS HAVE SPENT ON TRAVEL, LUXURY HOTELS AND FINE DINING. WE WILL CONTINUE TO BE COMMITTED BY DOING THE HARD WORK AND THE HEART WORK. Reporter: THIS WAS LAURA MIMES LATE LAST MONTH SPEAKING ABOUT THE FUTURE OF THE ACADEMY. AND SHE WAS HIRED TO TURN AROUND THE STRUGGLING OAK CLIFF CHARTER TODAY, BUT TODAY SHE NOTIFIED PARENTS SHE WAS QUITTING FOR PERSONAL AND MEDICAL REASONS. IN HER TWO YEARS ON THE JOB, THE DISTRICT’S ENROLLMENT HAS DROPPED AND THE SCHOOL HAS FAILED TO MEET STATE STANDARDS FOR STUDENT ACHIEVEMENT, RECEIVING AN AN F. GRADE. AND WHILE STUDENT PERFORMANCE HAS REMAINED LOW, RECORDS SHOW SPENDING BY THE TOP OFFICIALS HAS BEEN ANYTHING BUT. THE MONTHLY STATEMENTS FROM HER SHOWS TRIPS TO ATLANTA, D.C., SAN ANTONIO AND SAN FRANCISCO, WITH STAYS AT HIGH-END HOTELS AND DINING AT EXPENSIVE RESTAURANTS, ALONG WITH DOZENS OF CHARGES TO SOUTHWEST AIRLINES, EVEN VALET PARKING AT DALLAS’ LOVE FIELD. ON HER MARCH 2017 STATEMENT ALONE, SHE HAD MORE THAN $3,000 IN SOUTHWEST AIRLINE CHARGES, ALONG WITH A $3,500 CHARGE AT THE RESTAURANT IN DALLAS. THAT SAME MONTH SHE SPENT $4,700 AT HOTELS, INCLUDING MORE THAN $2,500 TO THE RITZ CARLTON IN SAN FRANCISCO. OH, MY GOD THAT IS A LOT. Reporter: THE PARENTS TODAY WERE SURPRISED BY THE SPENDING RECORDS WE SHOWED THEM. AND ALL OF THIS IS FROM THE SCHOOL ACCOUNT? Reporter: YES. I COULDN’T DO THAT AT MY JOB, IF MY JOB GAVE ME AN ACCOUNT. Reporter: AT A SCHOOL WHERE 90% OF THE STUDENTS ENROLL RED ECONOMICALLY DISADVANTAGED, MANY SAY THE MONEY SHOULD AND COULD BE SPENT BETTER. AND IT IS A LOT OF KIDS THAT NEED EXTRA HELP, YOU KNOW, THE PARENTS THEY CAN’T AFFORD BOOKS. THEY CAN’T AFFORD SCHOOL SUPPLIES AND STUFF. THAT MONEY COULD HAVE WENT TOWARDS — THAT IS A LOT. Reporter: IN OUR OPEN RECORDS REQUEST, WE ASKED THE SCHOOL FOR AN EXPLANATION OF CHARGES, AS WELL AS ITEMIZED RECEIPTS SO FAR WE HAVEN’T RECEIVED EITHER. WHEN WE ASKED THE SCHOOL BOARD PRESIDENT THIS EVENING WHETHER THE TRAVEL CHARGES WERE ALL SCHOOL RELATED, HE SAID I WOULDN’T HAVE THE SLIGHTEST IDEA. SO LAST MONTH THE SCHOOL BOARD CHANGED THE CREDIT CARD POLICIES. THE BOARD PRESIDENT TOLD US THIS EVENING THAT THAT MOVE WAS MADE FOR BETTER ACCOUNTABILITY. ACCORDING TO STATE RECORDS, HER SALARY LAST SCHOOL YEAR WAS $3 15,000. THAT IS A $75,000 INCREASE FROM THE YEAR BEFORE. NOW, WE SPOKE TO HER EARLIER TODAY BY PHONE. SHE DECLINED TO COMMENT ON THE RECORD. WITH THE I-TEAM, BRIAN NEW, CBS 11 NEWS. THANK YOU. THE CBS 11 I-TEAM IS ALWAYS THERE AND ALWAYS AVAILABLE BY E- MAIL.
