Sparks has now been charged with murder and is currently booked at the West Valley Detention Center.
Sparks Hated the Menards
As the investigation continues, the discovery of the human remains is shocking to the Olive Dell Ranch community.
Most residents at the nudist community knew and liked both the Menards and Sparks.
According to Tammie Wilkerson, a member of the nudist resort, Sparks harbored a deep-seated hatred for his elderly neighbors. “He didn’t like them,” Wilkerson told KCAL. “He hated them, and he told me that many times.”
Wilkerson explained that Sparks’ animosity stemmed from a seemingly trivial issue involving a tree on the property line.
“It’s such a stupid reason,” she said. “They had a tree that was on their property line, and Dan used to go trim the limbs, and [Sparks] hated that. That formed his hatred towards them.”
She also revealed that she had driven Sparks, known by his neighbors as “Sparky,” to the store several times to buy materials for constructing an underground shelter. The human remains were found in the concrete shelter.
