A Honolulu police sergeant charged in a corruption-related investigation targeting the department’s former chief and his former prosecutor wife is pleading guilty.

Court records show Sgt. Daniel Sellers is scheduled to change his plea next week. He previously pleaded not guilty to charges of lying to a federal grand jury and the FBI. It’s not clear what charges he’s pleading guilty to. Defense attorney Richard Sing declined to comment.

Sellers is one of several current and former officers charged in a federal investigation that accuses retired Chief Louis Kealoha and his wife Katherine Kealoha of orchestrating the framing of her uncle for the theft of the couple’s home mailbox.

U.S. prosecutors say the Kealohas wanted to discredit the uncle in a family financial dispute.

The Kealohas have pleaded not guilty.
