Crazy Kenneth Myers, 46, led cops on a deadly high speed pursuit before leading them to the scene of the family slaughter in Columbia, SC.
Myers' wife, 25-year-old Angela; her twin sister, Tabitha Brown; her mother, 50-year-old Vicki Brown; and Myers' ex-wife, 47-year-old Esther Baldwin were all found executed from single gunshots.
Investigators spent all night trying to piece together why Myers might have gone on the killing spree. Deputies weren't immediately familiar with him before Saturday night.
"It's hard to say at this point in the investigation why those people were killed," Aiken County Sheriff's Capt. Charles Barranco said.
