Melbourne woman Linda Chapman is searching for answers after her son Jack died after injecting his scrotum with silicone.

In a preview for tonight's episode of The Project, Ms Chapman confronts the man she holds accountable for Jack's death — his BDSM 'master' Dylan Hafertepen, who she claims her son was in a relationship with.

Jack, who lived in Seattle in the United States, was one of several of Mr Hafertepen's "pups" who followed his rules on body modification and bodybuilding.

"It was devotion, it was like some sort of clan, family, Like a cult. And to prove their devotion to him they had to change their bodies," Ms Chapman said.

Tragically, Jack died from silicone injection syndrome after the substance was injected into his scrotum.

Ms Chapman didn't learn her son was gravely ill until a day after he died.

"I didn't know he was in hospital, I didn't know he was in an induced coma, I never got to hold him, I never got to hug him. I never got to say goodbye," she said.

"And he (Hafertepen) waits til the day after he's dead to tell me he's dead. I didn't even know he was sick."

She also didn't know that Jack had changed his will three weeks before his death so that Mr Hafertepen would inherit his A$200,000 inheritance.

In heated scenes filmed by The Project, Ms Chapman can be seen confronting Mr Hafertepen with a photo of her son, after he flew to Australia to return Jack's ashes to his family.

"What sort of person injects into their friggin' balls?" Ms Chapman asks, fighting back tears during the emotionally charged exchange.

"What sort of person does that? Someone who feels so badly about themselves, someone who was vulnerable, who just wanted your love at any cost … and the cost of his life. You are the one responsible for Jack's death."
