(NewsNation) — Months after David Harrington, Clayton McGeeney and Ricky Johnson were found dead in a Kansas City backyard, their families continue to plead for answers.

Harrington’s mother reportedly wants Jordan Willis, who allegedly gave the three men illegal drugs prior to their death, to face charges.

Willis lived in the home where his friends were found dead, and he reportedly told police the men froze to death as temperatures dipped below freezing in the area.

After the incident, Willis reportedly checked himself into rehab. Police say they have no evidence of foul play. And autopsy and toxicology results are not public but reportedly showed the three men had cocaine and fentanyl in their systems.

McGeeney’s cousin, Alan, said he doesn’t think blame should be placed on Willis.

“I understand a mother’s pain, searching for some sort of understanding, looking for blame. But I don’t know if the blame would be on (Willis). I don’t think Jordan is to blame here. He wasn’t much different than my cousin Clayton. I personally don’t feel the same way,” he said during a Monday appearance on “Elizabeth Vargas Reports.”

Alan says regardless of charges, he’s hopeful that his cousin’s death can save someone else’s life and is turning family’s tragedy into a platform to talk about the fentanyl crisis.
