So heartbreaking. Last month, Frankie Rzucek‘s family suffered three devastating losses after his 34-year-old sister Shan’ann Watts and her two daughters, 4-year-old Bella and 3-year-old Celeste, were killed in an alleged triple murder at the hands of Shan’ann’s husband Chris Watts. But since their murders have become national news, Frankie and his family have received an outpouring of support from concerned citizens, and he took to his Facebook page to share a heartfelt message about how his family has been coping with the tragedy.

“Never in my wildest dreams would I have ever dreamt such a horrific nightmare and just plain heartbreaking tragedy would ever happen to my regular ol’ [sic] happy family,” he wrote on Facebook. “Our whole world was flipped on its head and changed our lives forever. We lost so much in a blink of an eye, but we also gained love and support from people all over and they became part of our FAMILY. I’ve never felt so loved in all my life, we can’t thank you all enough. May God bless each and every one of you. We love you all… The Rzuceks.”

Shan’ann and her daughters were reported missing by a family friend on Monday, Aug. 13. At the time of her disappearance, she was allegedly 15 weeks pregnant and she was last seen in the Frederick, CO area where she lived with her family. The following day, Shan’ann’s husband Chris, 33, gave an emotional interview to a local news station ABC 7 Denver, pleading for Shan’ann and his girls to come home.

But that Wednesday, Chris was arrested and charged with five counts of first-degree murder, a single count of unlawful termination of a pregnancy and three counts of tampering with a deceased human body, according to NBC News. According to People, Chris remains behind bars without bond and he has not yet entered a plea.
