His father Patrick Lambert is in custody. They were found in Queretaro, Mexico, about 10 hours south of the border, and are expected to return to the U.S. soon.
Houston police are calling Lambert a person of interest in the murder of little Achilles’ mother.
Anastacia Oaikhena Lambert’s decomposing body was found earlier this week stuffed in a refrigerator inside the couple’s apartment. Police say she was stabbed to death.
