Before his arrest, the man charged with killing two middle school girls in Indiana repeatedly told police during a lengthy and at times testy interview that he had nothing to do with their deaths.

On Thursday, the prosecution rested its case in the Indiana murder trial for Richard Allen, accused of killing Delphi teens Abby Williams and Libby German in 2017. But not before a very important piece of evidence was introduced: seven phone calls made from prison to his wife and mother in which he confessed to murdering the girls.
