A 71-year-old German woman has been charged with drowning her 5-year-old grandson in a bathtub while vacationing in the Florida Panhandle.

Marianne Bordt of Nufringen, Germany, was being held Tuesday at the Franklin County Jail in Eastpoint. She is charged with first-degree murder in the death Monday of Camden Hiers of Roswell, Ga., on St. George Island.

The woman's husband, Heinz Bordt, told sheriff's deputies his wife said she drowned the boy because she didn't want to see him growing up in a divorced home, authorities said.

Investigators said the husband came back from shopping to find his wife wet from the neck down. He told deputies she said she tried to kill herself in the Gulf of Mexico after drowning their grandson, authorities said.
