June Lynn Howard was 27 and a mother of three when she disappeared from Kennewick, Washington, after an evening errand on June 16, 1978. Her husband, Steve Howard, said she walked to a nearby 7-Eleven between 8 and 9 p.m. to buy cigarettes and never returned. He did not report her missing for eleven days.

Investigators found Steve’s accounts inconsistent; he gave differing stories to family, friends, and police, suggested June might have left voluntarily, agreed to a polygraph but never took it, and later moved to Louisiana. Co-workers said he did not seem overly concerned. Decades later a retired detective reviewed the file and authorities concluded June had been murdered by her husband. Steve Howard died in 2000 and was never charged.

One theory posits her remains were disposed of in a large heated acid tank at the husband’s auto repair shop, which could account for the lack of physical evidence. June remains in the national missing persons database; her children never received a direct answer about what happened to her.

If anyone knew June, her routine that night, or the Howard family’s activities in 1978, can you help provide information?
