A woman from Roxbury Township has admitted she tried to poison her grandmother by spiking her juice with antifreeze.

Elise Conroy, 27, was charged with attempted murder when she was arrested last summer.

Conroy pleaded guilty Tuesday to aggravated assault in a plea deal with prosecutors.

Prosecutors will recommend she receive five years' probation in her sentencing in September.

Conroy, who lived with her 83-year-old grandmother, bought the antifreeze last July with the purpose of poisoning her.

According to prosecutors, Conroy poured the antifreeze into some juice the next day and gave it to her grandmother, but she didn't drink it because it "tasted weird."

Conroy's attorney has said she wanted to injure her grandmother due to 17 years of alleged mistreatment.

The grandmother died in March after a heart attack.
