LOS ANGELES (KABC) -- Christine Cavanaugh, the woman behind the voice of Chuckie Finster from "Rugrats" and other beloved children's characters, has died. She was 51.
Cavanaugh died in her home state of Utah Dec. 22, her sister Deionn Masock confirmed Tuesday. Cavanaugh's obituary was also published in the L.A. Times. A cause of death was not released.
