Authorities have identified a Worthington, Minn., woman killed in an attack by her mentally ill grandson.

Darlene J. Broste, 86, was removed from life support July 9 after she suffered skull fractures and internal bleeding from the assault the day before in Maple Grove.

David R. Ekers, 34, of Plymouth, is charged with intentional second-degree murder in her death. He also faces two counts of attempted second-degree murder in the assault of his mother and sister, who were seriously injured, according to the Hennepin County Attorney's Office.

Ekers remains jailed in lieu of $1.5 million bail, with his next court appearance set for Aug. 4.
