The Norman Police Department closed its investigation into the alleged abuse of a 60-year-old Alzheimer’s patient at Whispering Pines Nursing Center.

The patient, Carol Crow, was hospitalized with severe bruises in July, Julie Glass, her daughter, said.

Norman Police officer Jennifer Newall said the department found insufficient evidence of abuse or neglect to justify a continued investigation.

“We have to have probable cause to believe a crime has been committed and know the person who has done it in order to arrest or press charges against somebody,” Newall said. “If more information comes in, we are more than happy to look at it, but it has to be more than just ‘we think this person did it.’”

According to police records, an investigating officer tried to interview Crow, but her condition prevented her from remembering details of the incident. Newall said Crow’s account of the situation was critical to the continuation of an investigation. The case will remain closed until more credible sources come forward with information.

Other than Crow’s family members, no one else affiliated with Whispering Pines has come forward with information about abuse at the facility, according to the police.

Wes Bledsoe, founder of A Perfect Cause, an advocacy group for nursing home residents, and Crow’s family said they are not satisfied with the way the authorities have handled the situation.

Bledsoe said he will continue to urge Cleveland County District Attorney Greg Mashburn and Okla. Attorney General Drew Edmonson and other authorities to ensure nursing facilities are held accountable for the care they provide.

“The facility is saying that they’re providing good treatment and, from what I’m hearing, that’s not true,” Bledsoe said.

If more evidence surfaces, Bledsoe and Crow’s family said they will take action in civil court.

Glass wants to see “granny cams,” which would be placed in nursing home residents’ rooms and common areas, in all nursing homes.

As for Crow, her health has improved since the incident in July. She is now at a nursing center in Muskogee, where she receives 24-hour care from a private nurse.

“She has improved so much. You can tell that she feels safe and has an improved quality of life,” Glass said.
