(CNN) The FBI has asked the public's help in locating a 32-year-old man they say is on the run with his 3-year-old son after allegedly killing the boy's mother.

The boy is believed to be in danger, police said.

A state felony arrest warrant charges Jorge Ernesto Rico-Ruvira with one count of murder after he allegedly killed a woman in New Mexico and took off with their toddler son, the federal agency said in a January 10 news released published by the Roswell Police Department.
