During the 18 years Ralph Raced cars all over the Midwest she and the kids traveled with him and they were always there for " Dad". Dee was always sacrificing her needs to be supportive to Ralph and the kids. It was always family first.

A malignant tumor was detected December 8th 2017 and removed from her Colon January 4th of 2018. Dee was otherwise very healthy and with much deliberation she and Ralph chose to follow the Doctors suggestions and had her 1st Chemotherapy on March 7th of this year. There was the "normal" nausea that goes with this treatment. Otherwise no problems surfaced. Her 2nd treatment on March 21st caused negative effects and March 25th she was admitted to St Lukes Emergency room with the symptoms of a Chemo reaction. She was eventually diagnosed with Febrile Neutropenia, A condition known to be caused by Chemotherapy treatment. It has a 96 Percent mortality rate. She fought very hard to save her life but it slipped away every day for 23 days. She passed away April 17th at 10:43 P.M at St Luke's South with her husband and children at her side. No donations are suggested, but if you would like to do something for your loved ones, have them consider all options and all possibilities of any negative effects before they subject themselves to any type of Chemotherapy. There is a very good chance Dee would have lived many good years if the choice had not been to try Chemotherapy. She will be missed by anyone who knew her, she was "Special" not many made like her.
