Over two years have passed since Jen and Sarah Hart allegedly drove their SUV with their six adopted kids — Markis, 19, Jeremiah and Abigail, both 14, Devonte, 15, Hannah, 16, and Ciera, 12 — off the side of a California cliff.

Since then, friends, family, and onlookers of the story have struggled to understand how these seemingly loving parents could have performed such a fatal act; however, according to reports, there were plenty of warning signs.

After the family perished, information on alleged child abuse and domestic assault behind closed doors begin coming to light.

People are revealing the true facts and events that played a part in this tragedy, including the friends who producer Rachel Morgan says were initially “defending” the Harts.

She tells E! News in a statement, “It was important for us to go into the documentary unbiased and let the story tell itself in any way that it took form. I felt it crucial to allow the friends who were silenced by harassment to be able to speak their point of view.”

“I felt it was just as important to share the cold hard facts from the investigation and inquest without sugar-coating it,” she adds.

Unfortunately, investigators were unable to prove that the parents killed themselves and their children on purpose and said that questions may never be answered.

The documentary A Thread of Deceit: The Hart Family Tragedy will be available on VOD & all digital platforms on April 7 so viewers can come to their own conclusions.
