PUNTA GORDA, Fla. (AP) _ The husband of a 21-year-old mother who was kidnapped, raped and killed plans to sue a sheriff’s office over how it handled 911 calls about her disappearance.

Nathan Lee blames Charlotte County sheriff’s officials for not saving Denise Lee in January.

Four 911 calls tipped authorities to Lee’s struggle. Three were from Lee herself. Another caller said she saw a child screaming and banging on a car window. The caller was actually describing Lee, but no deputies were sent to look for the car.

Two 911 workers have been suspended.

Nathan Lee told NBC’s ”Today” on Friday that he hopes the wrongful death lawsuit will bring change.

Michael King is in jail and charged with killing Lee.
