Washington, D.C. ? A funeral home that helps handle veterans awaiting burial at Arlington National Cemetery left corpses in an unrefrigerated garage, hallways and on makeshift gurneys, according to a former embalmer who has given his photographs and notes to authorities, The Washington Post reported Sunday.

Steven Napper, a retired Maryland trooper who worked at the funeral home for nine months, said he saw as many as 200 corpses not properly cared for while working at National Funeral Home in Falls Church, Va., from May until he quit in February. National Funeral Home also embalms and stores bodies for four other funeral homes in the D.C. region that are all part of Houston-based Service Corporation International, the world’s largest funeral services conglomerate.

The Post reported that Napper’s documentation as well as the observations of three other employees and a grieving son have sparked an investigation by the Virginia Board of Funeral Directors and Embalmers. The newspaper also reported that several people said a board investigator had interviewed them in recent weeks.

Lisa Hahn, the board’s executive director, told the Post she could not confirm a current probe or talk about allegations.
