FOX5 Vegas - KVVUAMBER Alert continues for Idaho children

For a second day, an AMBER Alert for three missing Idaho children continues to run in Las Vegas.

Authorities believe the mother drove to Nevada, where she is believed to live, instead of returning her children to foster care. Bertha Alicia Guerrero Castro was only allowed 24 hours with her children.

Before that 24-hour period was up, she was stopped in Tonopha, Nevada for speeding. The AMBER Alert had not been issued at that time.

"The feeling is that she is still in Las Vegas, which is why we have continued that activation, the AMBER Alert into a second day," said Bill Fisher with the Nevada Broadcasters Association. 

Over radio and on television, an alert goes out about missing children. On Sunday, televisions and road signs in Las Vegas began showing it after Idaho authorities asked for help.

Authorities say Bertha Alicia Guerrero-Castro lives in Las Vegas and drove to Idaho to see her children.

Idaho police say Guerrero Castro has addiction problems and has abandoned her kids in the past. Police believe 5-year-old Esmerelda, 7-year-old Mirella and 9-year-old Ubaldo are in danger.

That's one of four circumstances that must be met in order to issue an AMBER Alert.

"[The child] has to be 18 and under and there has to be an abduction," Fisher explained. "Finally, we've got to have enough information to put out there."

And as this AMBER Alert continues into a second day, authorities are hopeful the right person is watching.

The FBI is now involved in the hunt. It is also believed Guerrero-Casto and the children could be in Phoenix, or possibly Mexico.

More information about the children, including the clothes they were wearing when last seen, is posted on Nevada's Amber Alert website.

Anyone with information about Guerrero-Lopez is urged to call 911, Crime Stoppers at 702-385-5555, or Idaho police at 208-454-7531.
