3-Year-Old New Mexico Boy Was Allegedly Abducted by Dad, Who's Accused of Killing Mom

The search continues for 3-year-old Osiel Ernesto-Rico, who is believed to be with his father — the man authorities allege killed his mother earlier this month.

The Federal Bureau of Investigation has gotten involved in the hunt for the New Mexico boy, offering a $10,000 reward for any information that leads to his whereabouts.

The FBI also wants information about Osiel’s father, Jorge Ernesto Rico-Ruvira, and where he might be.

Investigators contend Rico-Ruvira may have fled to Mexico, where the father has ties to the areas of Zacatecas and Jalisco.

The two were last seen in the Roswell area.

Police believe the boy is in danger.
