Last Thursday, Yunique Morris, a 15-year-old Weston Ranch High School cheerleader, passed away, and her family is now demanding answers from the hospital that they say refused to address the problems threatening her health.

According to KTLA sister station KTXL, Morris had gone to see her doctor at San Joaquin General Hospital two weeks ago, complaining of chest pain. Her grandmother, Yunique’s grandmother, Wanda Ely, said that she was diagnosed with chest wall pain, given antibiotics and pain medication and placed on bed rest.

“Her health just started going downhill,” Ely said. “It got to the point where she couldn’t even go up and down a flight of stairs without getting out of breath.”

When she went back to the doctor a few days later, doctors insisted that it was a minor illness and that she was experiencing inflammation. However, on Thursday, Morris sent a text to her grandmother: “I NEED TO GO TO THE HOSPITAL, I JUST PASSED OUT, I’M THROWING UP NOW.”

Her older brother took her to the hospital, where San Joaquin General doctors found multiple clots in her chest. She died only hours later.

Now, her family is demanding answers from the hospital, claiming their negligence is what led to Morris’ death. They have also launched a GoFundMe campaign in order to pay for funeral expenses.

The exact cause of death will not be determined until next week, according to the family.
