An Oklahoma prosecutor is considering felony grand larceny charges against a Wal-Mart manager and his stepdaughter after another man stole about $78,000 from the store while disguised as an armored truck driver.

An Oklahoma State Bureau of Investigation agent Derek White, in court documents, says 43-year-old Rico Robertson and 21-year-old Mariah Bustamonte conspired with other family members in the Saturday robbery. They were arrested Wednesday. Online jail records didn't list attorneys for either suspect who could comment on the charges.

Bristow police say another man entered the Wal-Mart dressed similarly to a Loomis armored transport employee. They say he walked to the cash office, signed for the money and strolled out of the store. Employees called police when the real Loomis employee arrived.

No other arrests have been reported.
