A nurse for a VA hospital in Houston, Texas, allegedly said she had checked in on an elderly veteran several times on the night he died.

Not true, say federal prosecutors.

At the time of James Duplechain’s death, Christiana Ogbonnaya, employed as a nurse, faces charges for allegedly creating or utilizing false documents. Prosecutors allege an eight-hour gap occurred between her last check on him and discovering him unresponsive.

Her lawyer did not immediately respond to a request for comment from Law&Crime. Additionally, when reached for comment, the defendant herself reportedly disconnected the call, as noted by Houston ABC affiliate KTRK.

“This person is no longer employed by the VA,” the Houston VA conveyed in a statement to the outlet. “The allegations are horrifying, and the Houston VA is fully cooperating with law enforcement as the investigation progresses.”

Duplechain’s wife told the outlet that she believed he might still be alive if Ogbonnaya had checked in on him that night.
