Authorities say a man suspected of abducting a 16-year-old Southern California girl and triggering a multi-state Amber Alert might be armed with homemade explosives.
San Diego County Sheriff's Capt. Duncan Fraser said Thursday that evidence recovered at James Lee DiMaggio's home east of San Diego suggests he might have fled with explosives.
Meantime, Washington State Patrol said it has received several reports of possible sightings of DiMaggio's car. Sgt. Jason Hicks said people up and down the Interstate 5 corridor have reported seeing the blue Nissan Versa being sought by authorities. Some reports came in from the Vancouver, Wash., area; some from the Tacoma area; and at least one near Bremerton.
Troopers have been responding to each report but haven't located the car.
The search for Hannah Anderson and her younger brother has reached four Western states, Canada and Mexico. The FBI and various state and local law enforcement agencies are assisting.

Fraser says it's possible DiMaggio was infatuated with the girl. Her mother was found dead at DiMaggio's burning home near a dead child who might be the girl's younger brother, Ethan Anderson. Police are awaiting DNA test results to identify the remains.
Ethan Anderson is 4-foot-11, 65 pounds with sandy-colored hair.
Hannah Anderson is 5-foot-7, 115 pounds and has blond hair and blue eyes.
DiMaggio is 5-foot-9, 150 pounds with brown hair and eyes.
The three are believed to be in a blue Nissan Versa with California license plate number 6WCU986.
Authorities reported possible sightings of DiMaggio's car on Wednesday near Alturas, Calif., and Lakeview, Ore., and Thursday near Bremerton, Wash.
Anyone with information on their whereabouts is urged to contact Washington State Patrol at 253-538-3240.
