Donella Jean Coultas, 29, was last seen on December 18, 1979, in South Pasadena after a domestic argument with her husband, Leonard Coultas. Leonard told police she left the house angry with about $50 and a credit card; the card was never used and Donella’s purse, wallet, wedding ring, and keys were all left at home.

Leonard later admitted the argument turned violent, saying he struck Donella with a vase and that she bled from her nose and ears, yet he has denied involvement in her disappearance. Police treated Leonard as a suspect early in the inquiry, but some evidence was lost and no charges were filed. Donella was an executive secretary and mother of a two-year-old son. The Los Angeles County Sheriff’s Department continues to investigate and the case remains unsolved.

Did anyone in South Pasadena in December 1979 see Donella or know more about her movements after she left that day?
