A federal grand jury has indicted former Honolulu prosecutor and her brother on drug distribution charges.

The indictment unsealed Tuesday also alleges Katherine Kealoha, the wife of now-retired Honolulu police chief Louis Kealoha, steered law enforcement away from scrutinizing her brother, Dr. Rudolph Puana, after police told her that he was buying cocaine. Puana is an anesthesiologist.

Messages left Tuesday for lawyers for both siblings were not immediately returned.

The indictment charges the siblings and unnamed co-conspirators with distributing oxycodone, fentanyl and Xanax.

It says Puana advised one co-conspirator to use proceeds from the sale of illegal prescription pain medication to buy cocaine for the two of them.

Kealoha and her husband are scheduled to go to trial in March on unrelated charges.
