On Thursday morning, police announced the arrest of 23-year-old Amanda Fraser.
Kery Kilgannon told Eyewitness News on Wednesday that home security footage captured the moment his 84-year-old mother, Wendy Wilson, was stabbed by her overnight caregiver while she was asleep.
He says video shows the caregiver, believed to be Fraser, climbing into bed with Wilson before leaving the house.
Kilgannon says what happened next is a little unclear, but he says outside security footage appears to show the aide trying to hit the house with her car before fleeing.
Wilson wasn't discovered until Wednesday morning, when the daytime caregiver arrived.
Family members say Wilson suffered a punctured lung and is recovering from surgery.
Fraser was also brought to a Nassau County hospital for evaluation after her arrest was arraigned at her bedside for the second-degree attempted murder charges. She is being held without bail.
Her next court date is scheduled for Monday, November 3.
