Court documents show Welborn befriended many members and performed extra services for them, such as reconciling accounts and helping them pay bills, even though she was not required by the credit union to provide these services.

In addition to targeting accounts of members who were ill, near death or who lived out of town, Welborn also targeted accounts of members that she knew were not receiving monthly balance statements.

Federal prosecutors said Welborn would redirect some credit union members' mailed statements to the bank so account holders would not notice their accounts were missing funds. And when account holders wanted statements, Welborn would mail them fraudulent statements. To keep track of the stolen money, she kept a handwritten ledger with amounts taken from each account.

Eventually, according to court documents, Welborn would write checks payable to the credit union's bank (Country Club Bank) if there was not enough cash on hand at the credit union for her to steal. Country Club Bank would cash the checks because Welborn would indicate that the funds would be used to replenish the “petty cash account” at the credit union.

In 2010, when the credit union changed its correspondent bank to Missouri Corporate Credit Union, the “petty cash” replenishments went directly to the main office in Lansing. Because Welborn did not have access to sufficient cash on hand to steal, she began taking the money out of members' accounts.

Welborn also took money out of the credit union's vault, according to court documents. Although the money in the vault was supposed to be counted by at least two employees, Welborn had been covering her tracks by using her son who was working with her at the VA Medical Center branch.

“Welborn would often tell her son….the vault was counted and there was no need for him to do it,” court documents state.

Welborn's son has not been charged by federal prosecutors.

When the credit union became aware of the fraud, an accounting firm was hired to conduct a comprehensive audit, which revealed Welborn stole $304,000 from 23 credit union members from Jan. 1, 2009 to Jan. 26, 2012.
