WOODBURY - A 43-year-old Brooklawn woman has been indicted on a first-degree murder charge in the antifreeze poisoning death of her grandmother-in-law.

The grand jury returned the indictment of Anne Castagna this week. Castagna is accused of poisoning 88-year-old Mary Groatman, while Groatman was at a rehabilitation center in Deptford Township. Groatman was found unconscious after Castagna visited her Aug. 19, 2012, authorities said. Groatman died days later after she was taken off life support.

Castagna, who has not made $250,000 bail, remains in that county jail, a spokesman for the Gloucester County Prosecutor's Office said.
