(CNN) -- James DiMaggio -- the California murder suspect who allegedly kidnapped 16-year-old Hannah Anderson -- was shot and killed in the Idaho wilderness, authorities said Saturday.

An FBI tactical agent killed DiMaggio around 5 p.m. (7 p.m. ET) near Morehead Lake, San Diego County Sheriff Bill Gore said. The teenage girl was found alive near him.

"She appears well and was rescued and will be transported to a hospital in Idaho," Gore said.

Hannah Anderson was last seen at her cheerleading practice August 3; her mother and brother died in a fire at DiMaggio's home in San Diego County the next day.

About 250 law enforcement personnel -- among them about 150 FBI agents -- had converged on the River of No Return Wilderness, about 15 miles outside Cascade, looking for DiMaggio and his captive.

In addition to guarding all ways out, they tried to cover 300 square miles of rough terrain frequented by nature lovers near where DiMaggio's car was found Friday. Its license plates removed, the vehicle was hidden by brush in the vast River of No Return Wilderness.
