Roberta A. Butler, 52, was found dead in her Benicia townhouse on February 27, 1995. Her son, Jack Barron, discovered her in bed; investigators reported signs consistent with smothering.

Roberta’s death came after three other unexplained deaths in Barron’s immediate family over less than three years: his wife Irene died June 6, 1992 in Sacramento County of asphyxiation; their son Jeremy, age 4, was found unconscious and pronounced dead February 7, 1993; and their daughter Ashley, age 4, died under similar circumstances on August 7, 1994. After those deaths Barron sold his house and moved in with his mother.

A joint task force from Solano and Sacramento counties was formed to investigate the four deaths. Jack Barron was arrested on suspicion of murder with special circumstances and held without bail, with authorities saying they would not file charges in Roberta Butler’s death until pursuing a case in Sacramento County. Does anyone have information about the timeline or connections among these four deaths?
