for an alleged murderer and kidnapper was expanded Thursday after
authorities received possible sightings of the suspect's vehicle in
northern California and Oregon.
James Lee DiMaggio, 40, of Boulevard, Calif., is suspected of killing
Christina Anderson, 44, and abducting one or both of her children,
Hannah, 16, and Ethan, 8.
While an Amber Alert remains in effect for both children, authorities
said it's possible a second body recovered from the scorched home where
Anderson was found could belong to her son, Ethan.
"We're hopeful within the next day or so [we'll have confirmation], but
there has been some difficulty," Capt. Duncan Fraser of the San Diego
Sheriff's Department told ABCNews.com. "Because of the intense heat and
the fire, it has become very problematic finding usable DNA on the
Until authorities have confirmation that the body is Ethan Anderson,
Fraser said an Amber Alert will remain in effect for both children.
Fraser said the San Diego County Sheriff's Department has been in
contact with their counterparts in Canada, since it is believed DiMaggio
could try to cross the border. Authorities have also been working
closely with Mexican authorities, he said, since San Diego County is
located on the U.S.-Mexico border.
"At this point the suspect could be anywhere," Fraser said.
On Tuesday, the children's father, Brett Anderson, made no mention of
his son when he issued an emotional plea to DiMaggio, asking that his
daughter, Hannah, be let go.
"I'm begging you to let my daughter go. You've taken everything else,"
Anderson said at a news conference. "Hannah, we all love you very much.
If you have a chance, you take it. You run. You'll be found."
DiMaggio and Christina Anderson "were in a close platonic relationship," according to the sheriff's department.
Angelina Amati, a family friend of the Andersons', told ABC News' affiliate KGTV that DiMaggio had a crush on Hannah Anderson.
"I honestly believe that Jim has snapped and couldn't handle the infatuation that he had with Hannah," she told KGTV.
The Anderson children were last seen about 5 p.m. Saturday, according to Fraser.
About 8 p.m. Sunday, fire officials were called to put out a blaze at
DiMaggio's Boulevard, Calif., home and its detached garage.
Inside, they found Anderson's body, the body of what appeared to be a
child and a dead dog, according to the sheriff's department.
DiMaggio was last seen driving a blue Nissan Versa with California
license plates, is believed to be heading to either Texas or Canada,
according to California Highway Patrol.
