Four employees at an Oklahoma Department of Veterans Affairs facility have resigned after a resident with a maggot-infested wound died while under their care.Vietnam veteran Owen Reese Peterson, 73, initially came to the Talihina Veterans Center with an infection, but ended up with sepsis and died on Oct. 3.Sepsis is a potentially life-threatening complication of an infection that can damage the internal organs, causing them to fail.Peterson had apparently been at the facility for just a few weeks, and the time frame between the gruesome discovery of the maggots and his death is unclear. He did not succumb as a result of the parasites,  Executive Director Myles Deering told the Tulsa World.  He succumbed as a result of the sepsis. A physician s assistant and three nurses, including the director of nursing, resigned in the wake of the investigation, said Shane Faulkner, a spokesman for the ODVA. All four chose to resign before the termination process began,  Faulkner said.   WND
