AUBURN (AP) — A man convicted of killing two young girls and a teenager 50 years ago in Alabama has been denied parole.

The Opelika-Auburn News reports that Edward Seibold’s case went before the parole board Wednesday. He’ll remain imprisoned and “pay another installment on his life” for the killings.

Seibold was convicted for the 1967 murders of sisters Mary Lynn Sinclair, 9, and Elizabeth “Libba” Sinclair, 18; and Mary “MayMay” Durant, 8, a close next-door friend in the Auburn neighborhood. Seibold was angry over a denied romantic relationship with the oldest Sinclair sister, Cathey.

Cathey told the board Seibold said “he planned to kill all the family,” even after his conviction, and that what she feels is a complete lack of remorse.

Alabama law requires Seibold be allowed a parole hearing every five years.
