MADISON, Wis. – Investigators contend a former Madison middle school principal ignored school spending rules to abuse district credit cards, and others under her charge seemed to follow her example.

Former Black Hawk Middle School Principal Kenya Walker resigned from her $106,466-per-year job on April 28 after taking medical leave in January – the same time the district hired an external audit into the school’s finances, the Wisconsin State Journal reports.

That audit was delayed somewhat because Walker cut off contact with auditor Shana Lewis shortly after her departure, but a report finalized this week reveals many issues with how the school managed 15 district-issued credit and procurement cards.

The report alleges Walker and other staff routinely ignored requirements to “sign out” the cards and “failed to submit receipts on a regular basis,” which meant “there are many charges on the various … cards that cannot be verified” without extensive investigation, the news site reports.

Many of the charges were for personal expenses, according to Channel 3000.

“We’re disappointed to learn of these actions from a former principal,” Madison superintendent Jen Cheatham wrote in a prepared statement. “Our principals in general do an excellent job of managing the finances of their schools and this is a rare but serious incident.

“We have full faith in the Black Hawk team, and I’m looking forward to moving forward and supporting our students and staff in finishing the school year strong.”

At least $10,635 in charges are not accompanied by receipts, including dozens of Uber and taxi rides throughout the district for Walker, who does not own a car or drive, as well as $91 in bus tickets to Chicago and a $470 cell phone bill for Walker’s sister.

Records show Walker admitted to spending on the rides and reimbursed the district for $604, and that the school reported the cell phone bill as fraud and canceled the card, according to the Journal.

Walker also “acknowledged she did not take any steps to enforce the rules regarding the use of the credit and procurement cards; that she often failed to record her use of the district’s credit and procurement cards on the index cards; and she often failed to submit receipts to verify her purchases on the District’s cards.”

“There were rules that were not being followed,” Madison School Board member Dean Loumos said, placing the blame for mistakes on Walker. “How much training do you need to get a receipt when you buy something? This was very sloppy work. That’s clear to everybody.”

The report noted that lax money handling policies at the school led to other problems, as well.

The Journal reports:

The report said a failure to secure the school’s cash box and safe after a math carnival in March 2016 resulted in the theft of at least $1,000 raised during that event. Administrators failed to investigate the missing money, the report noted, thwarting any effort to recover it and hold the thief or thieves accountable, the review noted.

Employees said the safe, located in the school principal’s office, had a door that was “quite heavy and difficult to maneuver,” so it was routinely left open, even when it contained cash or valuable items, the report said.

“Moreover, it was common knowledge among the staff that the safe was not locked and secured,” the report said. “There is no video surveillance camera to record the individuals who access the safe and there is not always someone present … to monitor who accesses the safe.”

The Journal the money problems at the school mirrored money problems in Walker’s personal life.

The former principal filed for Chapter 13 bankruptcy in Chicago in late February, and was also evicted from her Madison apartment in 2015. A court ordered the district in May to garnish her wages to pay back $8,550 in overdue rent and damages to the downtown Madison apartment.

Loumos said it’s unclear whether the district plans to pursue legal action against Walker to recover any funds.

“We’re going to continue to discuss this to find out exactly what our options are,” he said. “Now the important thing is for the Black Hawk folks to know exactly what happened, (while) the process to hire a permanent replacement has begun.”
