"Her main thing with this pregnancy was to carry them as long as she can," her husband Joey Rott told KWCH in February. "She wanted to carry them for 34 weeks. That was her number one goal, to have healthy babies."

The pregnancy seemed to go smoothly. She carried them 34 weeks before giving birth Jan. 29 to three healthy babies named Asher, Levi and Piper.

But a week later, Casi woke up with severe chest pains, family members said.

She went to the emergency room, and a CT scan showed she had a blood clot in her lungs. She was treated and released from the hospital and for a while, everything was back to normal.

She held her babies and went home to visit her 6-year-old and 2-year-old daughters.

"She got to spend four hours here tidying up the nursery how she wanted it," said Joey. "I brought the two girls back here at 5 o'clock. She got to hug them, kiss them and love on them for about five minutes before the issues started."

ABC News reported Monday that doctors believe a second blood clot caused the 36-year-old mother's death.

Family friend Hilary Thompson has started a GoFundMe page to raise money for the family. It has raised over $90,000, nine times the orignal $10,000 goal.

Rott said the community support is what led the family to move back to Clay Center.

"The community has been incredible," Rott said.
