A Roseburg woman whose 21-month-old daughter died after police said she was left unattended for hours in a parked car told authorities she thought she had dropped off the child at a daycare.

Nicole Marie Engler, 38, told authorities she found her daughter, Remington, unconscious and blue at about 4 p.m. Thursday outside Evergreen Family Medicine, where Engler worked as a nurse practitioner.

Engler rushed the child into the clinic, where her colleagues tried to revive the little girl. The child was then transported to Mercy Medical Center, where she was pronounced dead, according to police.

The temperature at the time was 79 degrees, according to Weather Underground.

Engler was subsequently taken into custody and lodged in the Douglas County Jail on suspicion of second-degree manslaughter, which carries a mandatory sentence upon conviction of 75 months in prison.

Engler is a family nurse practitioner at Evergreen Family Medicine. The Roseburg News-Review reported she is originally from Salt Lake City and has lived in Roseburg for nearly four years.

She graduated from nursing school in 2005, received her master’s degree in nursing in 2009 and has worked in pediatrics, women’s health and family practice, according to her LinkedIn account.

“I am an avid advocate against child abuse and neglect, domestic violence and cruelty to animals,” she wrote in her profile.

An average of 37 children die every year in the United States from heat-related deaths after being trapped inside of cars, according to the safety organization Kids and Cars.

“Even the best of parents or caregivers can unknowingly leave a sleeping baby in a car; and the end result can be injury or even death,” according to the organization’s website.

The Oregonian reported that in 2014 an employee of Intel in the Portland suburb of Hillsboro was charged with manslaughter after he caused the death of his 6-month-old daughter by leaving her in his car for hours outside his office.

Prosecutors eventually dropped all charges against the father, calling the incident a “tragic and unintentional accident.”

Thursday’s incident in Roseburg was the second in two days in the West, after an 18-month-old boy was found dead in a hot car Wednesday in Willits, California.

Police there arrested the boy’s mother, identified as 23-year-old Alexandrea Raven Scott of Trinidad, after they said she went to visit friends at 3 a.m. and left her son in the back seat for 10 hours.
