A search of a Southern California landfill has turned up no sign of a toddler boy and his baby brother believed killed by their father at their Orange County apartment.

Orange police Sgt. Dan Adams says investigators and two cadaver-sniffing dogs completed a search of the Brea landfill on Tuesday but turned up nothing.

He says it's not clear where or when a search for the children will resume.

Adams says police believe the children were killed along with their 31-year-old mother by their father, Shazer Fernando Limas last month.

Limas was arrested last week following a police chase and charged Monday with three counts of murder. He's being held without bail.
