Two care home employees have been fired after allegedly filming themselves taunting a grandmother with dementia.
Brayan Cortez and Jamie Montesa have also been charged with misdemeanor disorderly conduct over the cruel incident.
Margaret Collins, 91, can be seen in the footage lying in bed and flailing her arms as someone waves a hospital gown in her face.
The great-gran looks to be in distress she attempts to push it away.
The video, which appears to have been filmed on Snapchat, has emerged online and is captioned: "Margaret hates gowns".
It is accompanied with two laughing face emojis.
Her outraged family is now taking legal action against nursing home, The Abington in Glenview, Illinois.
They are seeking more than $1 million in damages and allege the nursing home turned a blind eye.
Her son Tom Collins told ABC 7: "She's waving her arms because of one reason. She doesn't have mobility to get away. That's the only option she has to protect herself."
The incident is understood to have happened days before Christmas last year.
Margaret's daughter, Joan Biebel, fumed: "[Is] this somebody's sick idea of entertainment?"
The family are also suing Cortez and Montesa.
Their attorney, John Perconti, added: "They had no right to have cell phones in there."
In a statement, the nursing home said: "The privacy and dignity of our residents are of the utmost concern at the Abington.
"Recently, two employees were immediately terminated when it was determined that they violated our standards and policies."
However Margaret's family claim the workers remained employed for weeks after initially being cleared by administrators.
A report from the Illinois Department of Public Health said The Abington failed to implement its own abuse prevention policy.
Margaret is no longer living there, but her family says the incident has left her with anxiety.
