The Amber Alert for a missing San Diego County girl allegedly abducted by a family friend was extended to Idaho on Friday, marking the fifth state included in the search for 16-year-old Hannah Anderson and her alleged kidnapper.
The Amber Alert for the teen and James Lee DiMaggio, 40, is also active in California, Washington, Oregon and Nevada.
DiMaggio was believed to be driving a blue Nissan Versa, California license plate 6WCU986, but authorities said Thursday he might have changed vehicles. Officials also said DiMaggio might have left the Nissan booby-trapped with explosives, warning people who may encounter the vehicle or anywhere he might have stopped to stay away.
DiMaggio is believed by authorities to have abducted the teenager Sunday after allegedly killing her mother and 8-year-old brother in Boulevard, a rural border town in eastern San Diego County, and setting his house on fire.
DiMaggio has been described as a close friend of the Anderson family, but his relationship to Hannah is unclear.
On Wednesday, the Amber Alert was broadened to include the Pacific Northwest states after a car matching the description of the Nissan was seen driving north on U.S. 395 near Alturas, Calif., toward the Oregon border.
Oregon state police Lt. Gregg Hastings said in a statement that a "possible sighting of the vehicle" was reported about 2 p.m. Wednesday in southern Oregon, but the sighting was not confirmed.
The Amber Alert extended into Nevada the next day.
On Friday, authorities in the other states said they were continuing to chase incoming tips about possible suspect vehicles.
Washington State Patrol Sgt. Jason Hicks said his agency "thought we had a close one yesterday" -- a blue Nissan Versa that was speeding north -- "but when we caught up to it, it was not the individual."
Authorities have said DiMaggio might have taken Hannah Anderson to Texas, or even Canada. Boulevard is also about five miles north of the Mexican border, and the FBI was working with Mexican authorities to search for DiMaggio.
Complicating search efforts is the fact that DiMaggio is an avid outdoorsman, prompting authorities to expand their net to include campsites and other rural areas where he might be hiding.
"Basically, the search area is the United States, Canada and Mexico," said Lt. Glenn Giannantonio of the San Diego County Sheriff's Department. "The search area is North America."
