The attacks are apparently the culmination of a long-running and increasingly bitter neighbourhood dispute between the Petkovs and a number of residents in Trenton, Michigan that have raged over the past couple of years.
Kathleen’s stepmother, Gabrielle Edward, told reporters that the feud started two years ago.
“Kathleen’s grandmother had a birthday party, and Jennifer sent a message asking if her kids could come over to play,” she said.
But the grandmother, Rebecca Rose, did not respond to the text quickly enough, she said. “That’s where it all started.”
When questioned on why she escalated the ugly feud, Jennifer Petkov said it was for “personal satisfaction”.
Kathleen’s father, Robert Edwards has appealed to the Petkov family, “Just leave us alone; that’s all we want. Don’t make anymore comments about our daughter.”
The family have been doing their best to shield their daughter from these taunts.
“There (are) more important things to deal with like our daughter, She’s hanging in there. We have hospice at home every week, and that’s a lot to deal with on its own,” her father said.
Family friend Michelle Yerigian, 42, told Fox News, “I don’t understand how people could spew such hatred. They would pull up in the truck with the coffin attached, rev up the engine, and say to Kathleen, ‘I can’t wait until you die.’”
“When I saw what she posted on Facebook, I almost threw up. I’m totally dumbfounded,” she said.
However, the couple in question have since come forward to apologise after being the target of global condemnation.
Mrs Petkov’s husband, Scott, 30, said the fallout of the Facebook posting resulted in his suspension with pay from his job as a forklift repairman in nearby Warren. He added that his employer is considering firing him.
“I feel horrible for what I’ve said and done. That little girl shouldn’t have had to lose her mum like that and she shouldn’t have to lose her life either. I just hope she didn’t see those pictures,” Petkov said.
