Authorities say a 25-year-old Maryland woman has died days after she and her two children were critically injured in a hammer attack.

Princess Anne Police Chief Tim Bozman said by telephone Monday that police were notified that Airealle Sells died over the weekend. Police say in a statement that her 8-year-old daughter and 4-year-old son are in critical but stable condition.

Sells' ex-boyfriend, 26-year-old Sharef Dontre Hayward of Baltimore, was charged with attempted murder. Bozman says investigators are consulting with the Somerset County State's Attorney's Office for modification of charges against Hayward.

Bozman says Hayward stabbed Sells and then assaulted her and the children with a hammer.

News outlets report that Sells was granted a protective order against Hayward a day before the attack.
