MINNEAPOLIS — The Department of Veterans Affairs said Tuesday it will investigate allegations that the appointment records of a retired Marine who died after having seizures were falsified to cover up delays in patient care at the Minneapolis VA Health Care System.

Cathy Gromek, spokeswoman for the VA’s inspector general’s office in Washington, told The Associated Press she wasn’t sure when the investigation would be finished.

“We’re working it and when we can report out, we’ll report out,” Gromek said.

The announcement followed calls from Minnesota’s congressional delegation for an investigation, one day after KARE-TV reported that VA records showed that a neurology exam for Jordan Buisman was rescheduled four days after his death. His family believes the record was falsified and has filed a wrongful death claim against the VA.

Buisman had been told he’d have to wait almost 70 days to see a specialist at the Minneapolis VA neurology clinic for his epilepsy, which had forced him to leave the Marines. The 24-year-old former corporal died Nov. 26, 2012 — 24 days before his appointment. His death certificate listed “seizure disorder” as the cause.
