The mother of a boy killed by a convicted murderer whose innocence Kim Kardashian is trying to prove said the reality show star has rekindled the pain and grief from her son’s death in 1983, according to a report on Sunday.

Mary Ann Hughes said she was disgusted to see photos of Kardashian embracing a smiling Kevin Cooper on death row last week at San Quentin State Prison in California.

“It makes me feel sick to my stomach and I pity her. For what she’s doing to us, there’s nothing to justify what she’s doing to us, the immense pain she is causing us,” Hughes told TMZ.com.

She said if the “Keeping Up with the Kardashians” star read up on the evidence in Cooper’s case, she would realize how guilty he is.

Kardashian “obviously has not read all of the actual evidence – she has bought into half-truths perpetrated by the defense. If she actually sat down and read the transcripts of all the trials and appeals, she would be sick to her stomach to be in the same room with him,” Hughes said.
