We did a podcast in October 2019 that included the story of Steven Wayne Benson, family annihilator. Steven planted a bomb in his car and then ushered his family inside it.
Pretending he needed something in the house, he left the car, standing on the porch steps as it exploded.
Steven’s mother and nephew died instantly. Steven’s sister was throw free of the car, suffering deep burns.
He killed to his family to get to their money.
A book was written about his crime: https://books.google.com/books?id=nL-mQROQPfQC&pg=PA139&lpg=PA139&dq=Steven+Wayne+Benson&source=bl&ots=Ct1cUKeQTy&sig=ACfU3U26eX_aJMcknR7k8j_JIfZk2d2u6g&hl=en&sa=X&ved=2ahUKEwjU86TBmezlAhVEXKwKHS-ABQMQ6AEwCHoECAgQAg#v=onepage&q=Steven%20Wayne%20Benson&f=false
