"Heaven gained another angel tonight. God knew she was too perfect for this world. We will love you forever, Mia Sofia," Mia's mother, Christina Klyczek, posted shortly before 10 p.m. Sunday. Mia's mother shared Friday on social media that an MRL showed no blood flow to her brain and four dead areas.

Mia Klyczek has passed away just days after testing positive for flu B, according to a GoFundMe page set up for her and a Facebook post from her mother.

Suse Lowenstein’s son was killed in the 1988 bombing of Pan Am Flight 103 over Lockerbie, Scotland. An artist, she responded by creating a huge sculptural installation, Dark Elegy, depicting the raw emotion women felt the day they learned their loved ones died.

The family of 9-year-old Mia Klyczek of Alden said doctors believe she died of complications from Flu B. Mia’s mother, Christina, said her death is the most unimaginable heartbreak, adding that they’re appreciative of the outpouring of community support and prayers.

I know she is with Jesus right now," Mia Klyczek's mom wrote. "But I hope He will change his mind and send her back for a little while longer.”
