Sol had invested $20,000 in Harvey Rader’s car dealership. Rader, a British citizen, was the last person seen with Sol.

The family’s home showed signs of a struggle: blood splatters, a missing carpet section, water running into the pool, and a baseball bat near the bar. Their beds were made, which was unusual. Five days later, some of their belongings (passports, wallets, photos) were found scattered along a freeway.

A year later, Rader’s cousin, Ashley Paulle, claimed he saw Rader shoot Sol and helped bury the entire family in the desert near Acton (where their belongings were found). Paulle initially got immunity for his testimony but later failed a lie detector test and was charged as an accessory. These charges were dropped, and he returned to England, refusing to testify against his cousin.

Rader was arrested in 1988 but his trial ended in two mistrials. He was ultimately acquitted in 1992, despite circumstantial evidence. Three witnesses claimed to have seen Sol alive after the disappearance. Rader’s defense argued Sol was involved in illegal activities and had marital problems.

Rader was also a suspect in another unsolved disappearance case but was never charged. Despite extensive searches, the Salomon family’s remains have never been found. The case remains unsolved.
