An Ohio woman who was stabbed while protecting her grandchildren from a man who lured the youngsters into an alley, died Wednesday from injuries sustained during the June 23 attack, Columbus Police said.
The children, a boy and a girl, were lured by Kristopher T. Amos, 29, into an alley under the guise of searching for his lost drone, police said.
The children's grandmother, Candy Arthurs, 45, confronted Amos in the alley. He then pulled a large knife and stabbed her in the chest, and stabbed her grandson Jeremy Mullins, 7, in the shoulder. Her 8-year-old granddaughter was not hurt.
Arthurs was rushed to Mount Carmel West Hospital, but she never recovered from her injuries, and she died more than a month later, on Wednesday, police said. Mullins was treated at Nationwide Children's Hospital and recovered.
Amos already been charged with 2 counts of felonious assault, but an additional charge of murder was added once Arthurs died.
He was arrested without incident Wednesday morning.
According to court documents, Amos is being represented by Thomas J. Port with the Franklin County Public Defender Office. ABC News has reached out for comment.
