The continuing search for missing 16-year-old Hannah Anderson, who is believed to have been abducted by James Lee DiMaggio, has been extended to all of the United States, as well as Canada and Mexico. 

“The search area is North America,” said Lt. Glenn Giannantonio of the San Diego County Sheriff’s Department, according to the Los Angeles Times.  

Anderson went missing six days ago after her mother was found dead, believed to have been murdered by DiMaggio, who then took off with Hannah in his blue sedan.

The search widened beyond California in the following days and Amber Alerts were activated for Washington, Oregon, and Nevada. Now, authorities aren’t sure where DiMaggio and Anderson are. 

Police are also warning that DiMaggio may have abandoned his car while on the run and rigged it with explosives.

The search for DiMaggio, 40, entered a sixth day Friday. “In the event that someone comes across the car, they need to use caution,” said San Diego County Sheriff’s Capt. Duncan Fraser.

In Mexico, for instance, airports, bus and taxi companies and law enforcement agencies were on the lookout, said Alfredo Arenas, international liaison for the Baja California state police.

“This is a pretty much an all-hands-on-deck effort. It’s huge,” Fraser said.
