Nurses at a Woodstock, GA nursing home lost their licenses after 11 Alive obtained video secretly recorded by the family of a man who died at that nursing home.

The video shows a patient, who was a World War II veteran, repeatedly calling for help and saying he can’t breathe. The nurses are then heard as they try to start an oxygen machine and fail to take life-saving measures.

The family of 89-year-old James Dempsey of Woodstock, Georgia, sued the Northeast Atlanta Health and Rehabilitation Center in 2014. A statement from the center says care has improved since then.

But WXIA-TV/11Alive says the nurses didn’t surrender their licenses until this September, after 11 Alive sent The Georgia Board of Nursing a link to the video the nursing home fought three years to keep secret.
