ROXBURY — A 26-year-old woman from the township's Succasunna section has been charged with attempting to kill her grandmother.

Elise Conroy is facing a first-degree attempted murder charge after feeding antifreeze-laced juice to her 84-year-old relative, the Morris County Prosecutor's Office said Saturday.

Investigators say Conroy purchased the antifreeze at a local store in July. She later poured the chemical into juice and gave it to her grandmother, authorities said.

Authorities believe the elderly woman drank the juice at least once. But the woman did not get sick.

Conroy was arrested Saturday morning and was being held at the Morris County jail.

New Jersey 101.5 did not know Saturday whether Conroy had an attorney who could speak on her behalf.

Ingredients in engine coolant, depending on how much is ingested, can cause death within 24 hours or lead to serious and permanent brain, kidney and vision damage.

Morris County prosecutors do not release arrest booking photos of defendants.
