On Monday's episode of Dr. Phil titled "Unforgivable Acts," the feud on Detroit Street took the national stage, just over two weeks after as a result of Huntington's disease.
Kathleen's father, Robert Edward, and stepmother, Gabby Edward, both of Wyandotte, and family friend Michelle sat down with Dr. Phil in his studio in Los Angeles before a studio audience.
Jennifer and Scott Petkov and Kathleen's grandmother, Rebecca Rose, joined the family in the studio live via satellite. Rose and the couple Dr. Phil said had been called "the cruelest couple in the world" were not together during the taping of the show.
Kathleen's family was on the show to tell their story and speak with Jennifer and Scott directly.
Jennifer Petkov first made national headlines after she admittedly , Laura Edward, who also died as a result of Huntington's, on Facebook. The photos depicted Kathleen in a skull and cross bones and Laura embraced by the grim reaper.
Dr. Phil tried to find the catalyst that began the feud, but a definitive answer was not found.
Each of Kathleen's family members was allowed chances to speak with the Petkovs. Dr. Phil also spoke to the Petkovs.
The Petkovs apologized for posting the photos, but denied doing anything else, while Kathleen's family insisted she "tell the truth."
At the end of the show, there was a glimmer of hope offered by Robert Edward, who said he forgave Jennifer.
He said he did not like her and did not want to be her friend, but hoped she could move on from the feud.
He added he wished he could get back the time he spent over the last year and as a result of the feud, so he could use that time to spend with Kathleen.
