Late summer 1972: William Oliver Peak III, 53, his wife Bernice and their 14-year-old daughter Barbara were attacked in their Grand Island, Nebraska, home. On the evening of September 9, 1972, all three were shot in the head with a .22-caliber firearm. William and Barbara were found dead at the scene; Bernice survived long enough to tell investigators there had been more than one assailant but died two months later of her wounds.

Investigators found no sign of a struggle and no evidence of theft or sexual assault; William’s wallet and credit cards were discovered in the street outside. Early leads ranged from a possible professional hit tied to Colonel Peak’s past as a military attaché in Russia and Hungary to local suspects connected with drugs and a mysterious car seen nearby, but those avenues produced no arrests. The Nebraska State Patrol investigated and the case was reviewed by the governor, yet the murders remain unsolved and the family has offered a reward for information.

Does anyone have information about the Peak family or the mysterious car that could help finally bring answers?
