MAIZE, Kan. (AP) — The former technology director for the Maize school system is among those accused in an ongoing lawsuit of defrauding the central Kansas district of more than $1 million.

The Wichita Eagle reports that the U.S. Attorney’s Office filed the civil case in 2014, although it wasn’t unsealed until this year. It stemmed from a federal investigation into a fraud, money laundering and kickback scheme that spanned more than five years and involved several vendors that were paid more than $4 million for technology-related services.

The investigation focused on former district employee Ramon Mosate, who committed suicide last year. The case seeks the forfeiture of a lavish northwest Wichita home previously owned by Mosate, about $80,000 in cash from a safe deposit box and about $5,400 in his checking account.
