SEATTLE -- A Seattle judge will consider a mother's request Thursday to keep her teenage sons away from a woman who killed her own daughters 20 years ago.

Trisha Conlon of Silverton, Ore., had two children with her former husband, retired Marine fighter pilot Lt. Col. John P. Cushing Jr., in the 1990s. But they split up several years ago, and John Cushing has since gotten back together with his first wife, Kristine, who killed their 4- and 8-year old daughters in California's Orange County in 1991.

Kristine Cushing blamed it on antidepressants and was found not guilty by reason of insanity.

Conlon says she doesn't want her boys living with their dad in Washington with Kristine Cushing in the house. John Cushing says Kristine loves the boys and poses no danger.
