An elderly northeast Kansas woman has died from injuries in a weekend shooting that also claimed her daughter and two granddaughters.

Kansas' attorney general announced on Wednesday the death of 89-year-old Dorothy Wight of Osage County.

Spokeswoman Ashley Anstaett said Wight died Tuesday at a Topeka hospital but the attorney general's office delayed the announcement until family members were notified.

The shootings Saturday occurred in Wight's home outside Burlingame.

James Kraig Kahler, 46, a former Columbia, Mo., city official already is charged with capital murder in the deaths of his his 44-year-old estranged wife, Karen, and their daughters, 18-year-old Emily and 16-year-old Lauren.

Authorities say their 10-year-old son, Sean, also was at the home but was not physically injured.
