On Monday, Frank Rzucek, father of Shanann Watts, delivered an important message in a TV press conference. Standing outside the home where his daughter lived in Frederick, Colorado, Rzucek requested that anyone who has been harassing his family online to "please, just stop," reports The Denver Post.

His plea was in response to unwanted attention his family has been receiving since his daughter and grandchildren were murdered by her husband, Chris Watts, in August 2018.

"... Our family, including Shanann and her children - and our grandchildren - have been ridiculed, demeaned, slandered, (and) mocked in the most vicious ways you can imagine," Rzucek said.

According to CNN, Shanann's pregnant body, along with the bodies of her children, Bella, 4, and Celeste, 3, were discovered last August in an oil field where her husband worked. Chris Watts later pleaded guilty and is serving five life sentences.

"Every time we turn around there is someone trying to capitalize on our tragedy by spreading false rumors and outright lies about Shanann and our grandchildren," Rzucek said.

Continuing, he said that they had been subjected to death threats, which has prevented them from being able to properly mourn, which, he said, "... is so wrong. It is cruel. It is heartless and it's flat wrong." However, Rzucek refrained from going into the specifics of what the online harassment looks like.

While Watts' father has called on social media platforms to amend their policies, he stated that they have not responded thus far. When addressing the companies, he said, "We are calling on you to do the right thing, to take some responsibility for your platform and stop this despicable conduct."

According to Steven Lambert, the family's personal attorney, they have contacted Facebook, Twitter, and YouTube regarding the harassment.

Rzucek also acknowledged that the family has, in contrast, received a lot of support as well, as reported by KDVR. "To the people who have stood with us, who have supported us and prayed for us and our family -- for Shanann and our grandchildren -- we can't thank you enough. God bless you all," he said.
