Messick's family says McGowan reported the incident to her without calling it rape, but that Messick, realizing something inappropriate if not illegal had happened, reported it to her senior bosses months before she went to work under Weinstein at Miramax.
They said: "She opted not to add to the feeding frenzy, allowing her name and her reputation to be sullied despite having done nothing wrong".
The family of the former Weinstein Company producer - who died age 50 after a battle with depression - claimed she was "victimized" after being dragged back into the headlines over McGowan's resurfaced 1997 rape allegations.
"She put her arms around me", McGowan told the paper.
'For Jill: May your family find solace during this pain.
'That one man could cause so much damage is astounding, but tragically true. The bad man did this to us both. "May you find serenity with the stars", her post continued.
One Twitter user wrote, 'Is this the first thing that you felt when you heard of your former manager taking her life and her family blaming among others your own contempt against Jill?
Weinstein has called McGowan's rape accusation "a bold lie" through his lawyer, claiming the actress told Messick soon afterward that the encounter was consensual. In a statement to the Associated Press, Messick's family described her as "collateral damage in an already horrific story". Over a successful career, she produced hit films including "She's All That", "Mean Girls" and "Frida" and had worked on the upcoming video game adaption "Minecraft: The Movie". She recently said that Messick, who was her manager at the time, failed to support her fight against Weinstein and then took a job with him.
When people realized Rose's first social media post since Jill's passing didn't acknowledge her at all, they were furious.
