Despite reported sightings of murder and kidnapping suspect James DiMaggio in California, Oregon and Washington state, authorities said Thursday that they still have no solid leads on his whereabouts.
Nevada became the fourth state to issue an AMBER Alert for a 2013 blue, four-door Nissan Versa with California license plates 6WCU986. Authorities in Canada and Mexico are also on the lookout.
California authorities have said DiMaggio may be headed to Canada or Texas with 16-year-old Hannah Anderson and possibly her 8-year-old brother, Ethan.
Charred remains of a child found with their mother in DiMaggio's burned down home east of San Diego have not been positively identified. Investigators said they were unable to obtain DNA from the body because it was too badly burned.
Citing a source, the Los Angeles Times reported Thursday that Anderson died from blunt trauma and may have been hit with a crowbar.
DiMaggio, a telecommunications technician at the Scripps Institution of Oceanography in La Jolla, Calif., may have fled with homemade explosives, San Diego County Sheriff's Capt. Duncan Fraser told KNSD-TV. He provided no details.
His car might be booby-trapped, the Associated Press reported.
Authorities have not said whether DiMaggio might also have firearms.
Dozens of tips have poured in from Oregon and Washington, but none of the reported sightings has panned out, homicide Lt. Glenn Giannantonio said.
"For all we know they could be hunkered down in the Cleveland National Forest camping or something and waiting until this blows over and then they're going to come out," he told KNSD-TV.
Friends said DiMaggio is an experienced camper.
Giannantonio described DiMaggio as desperate and dangerous, saying the kidnapped teen "is in grave danger."
This composite photo released by the San Diego Sheriff's Department shows James Lee Dimaggio, 40, suspected of killing a mother and possibly abducting her children.
DiMaggio, 40, became the subject of a nationwide manhunt after the bodies of 44-year-old Christina Anderson, of Lakeside, Calif., and an unidentified child were found Sunday night in his burning house in Boulevard, 50 miles east of San Diego. DiMaggio was a close friend of the family and known as "Uncle Jim."
Christina Anderson's father, Christopher Saincome, said his daughter and the children had visited DiMaggio's home to say goodbye before he moved to Texas, where he was born. A family friend said he was depressed because he had lost his home and had to leave.
The focus on the Northwest intensified after Oregon State Police reported a possible sighting of DiMaggo's car Wednesday near Alturas, in northeast Oregon, and later about 50 miles along the same highway near Lakeview, in south-central Oregon. Fraser called the tip "very credible."
In one unconfirmed sighting, Washington State Patrol Trooper Russ Winger told KOMO Radio that a driver near Bremerton, north of Seattle, reported seeing a blue Nissan hatchback on Highway 101 on Thursday morning with a man driving and a woman passenger.
A trooper checked the area but did not find the car.
Brett Anderson, Anderson's husband and the children's father, flew from Tennessee to San Diego on Tuesday and pleaded with DiMaggio to release Hannah, saying, "You've taken everything else."
"Jim, I can't fathom what you were thinking. The damage is done," he said Tuesday night outside San Diego County Sheriff's Department headquarters.
He also appealed to Hannah, saying he loves her very much and "if you have a chance, you take it. You run. You'll be found."
Authorities have said DiMaggio had a "close platonic relationship" with Christina Anderson.
Although DiMaggio was like family to the children, Hannah's friends said he had recently expressed different feelings for the teen.
"He said he had a crush on her, but didn't mean it in an intimate way," 15-year-old Marissa Chavez told The San Diego Union-Tribune. "He said, 'If I was your age, I'd date you.'"
The comment made the girls uneasy, Marissa added.
She said DiMaggio took Hannah to Hollywood for a week-long "Sweet 16" birthday celebration. The trip was cut short, however, because DiMaggio became upset about the amount of time Hannah spent on her cellphone.
"After that she never responded to his texts and e-mails," Marissa told the San Diego newspaper.
