ENGLEWOOD, Colo. (NewsNation) — A Denver woman’s body was discovered three days after she died in her car outside of a Colorado hospital.

Yvette Mooney’s body was discovered on Sunday, Aug. 23. She died Thursday, Aug. 20. She was 50-years-old.

Mooney didn’t answer any phone calls the day she died. Her family thought she had gone to Swedish Medical Center to visit a family friend. Her family called police after they didn’t hear from her.

Englewood officers discovered Mooney’s body in her car in the emergency room parking garage.

“She couldn’t make it inside,” said Kandra Garcia, Mooney’s daughter-in-law. “She thought, ‘I’m in an ER parking lot. They will find me — somebody will come.’ Not three days later when she’s blistered and too decomposed for us to have a proper burial.”

The hospital issued a statement after Mooney’s death.

“We offer sincere condolences and deepest sympathy to the family and loved ones. Upon discovery of the event we immediately notified the Englewood Police Department and have worked closely with them throughout the ongoing investigation.”

The family says they want changes in security policies so cars are checked more regularly.

“Somebody dropped the ball and I want answers,” Garcia said.

The Englewood Police Department said the coroner’s office is still determining Mooney’s cause of death.

Detectives are requesting surveillance video from the hospital, but say the car’s windows were tinted and it would be difficult to see inside the vehicle.
