(Connersville, IN)--There’s a new development in the case of Connersville’s Denise Pflum.  Denise was a teenager when she went missing back in 1986.  Now, her parents have filed a lawsuit to obtain an order to search property that has never been searched in an effort to find her remains.  The lawsuit has been filed against Erika Johnson, who is the sister of Benny Johnson.  He became a person of interest shortly after Denise disappeared.  Her car was found near the Johnson property.  Court documents also allege that Benny Johnson has confessed to some level of involvement to her disappearance.
