Frankie Rzucek expressed gratitude to everyone who has tried to help his family after his pregnant sister and her two young daughters were brutally murdered, allegedly at the hands of her husband.

As CrimeOnline previously reported, 33-year-old Chris Watts was placed on suicide watch after he was locked up on suspicion of killing 34-year-old Shanann Watts and their daughters, 3-year-old Celeste and 4-year-old Bella.

“I wanted to take a minute and thank everyone who has helped us in every way possible,” Shanann Watts’ brother wrote on Facebook this week. “From best friends and family to people from all over THE WORLD.”

As People reported, Rzucek did not mention the suspect in the murders by name in this post but has previously referred to him online as a “heartless psychopath.”

Instead, he focused on the importance of family, saying it is “truly an honor and a blessing” to have those around him and “all over the globe” who have sent condolences or served as “a listening ear.”

Rzucek went on to describe the “horrific nightmare” that has rocked his “regular ol happy family” since the murders last month.

“Our whole world was flipped on its head and changed our lives forever,” he added.

At the same time, he said his family has grown exponentially thanks to the outpouring of support the case has generated.

“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,” he wrote. “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.”
