St. Louis, MO – A traffic stop in St. Charles County Tuesday morning ended with a brother and sister confessing to murder.
Sheriff's deputies pulled over Kenneth Allen, Jr. and Kari Allen for speeding on I-70 (both are from Noblesville, Ind.).
Police then found bloody sheets in the trunk and say the two then admitted to killing their mother and grandparents in Indianapolis.
The two are in custody.
Investigators in Indianapolis are returning this (Wed.) morning to the house where they believe three bodies are buried in the basement's concrete floor.
The search was suspended early this (Wed.) morning when some human remains were found.
An anthropology team will sift through the concrete looking for evidence. Police says the search could take weeks.
