Authorities continue to search for a missing month-old baby who has not been seen since his mother, grandmother and great-grandmother were found dead in their Miami home late last month.

As CrimeOnline previously reported, baby Andrew Caballeiro has not been seen since January 28, after a relative found 40-year-old Arlety Garcia Valdes, 60-year-old Isabela Valdes, and 84-year-old Lina Gonzalez found shot to death at their home in the Redland neighborhood.

Authorities believe that Andrew was abducted by his father, 49-year-old Ernesto Caballeiro, who was found shot to death in his van on January 29. Police had previously issued an AMBER Alert for the missing boy and his father as authorities believed they were together. But when the elder Caballeiro was found dead, there was no sign of the baby.

NBC Miami reports that earlier this week, Miami-Dade Police searched a canal that runs along a road connecting Tamiami north of Everglades City in connection to the missing infant. Search crews visited the canal on Tuesday, along with a subsequent search on Wednesday involving a dive team, but they reportedly did not find any sign of the baby boy.

“This case remains active and ongoing. Investigators continue to follow all leads and are working diligently with local, state and federal law enforcement agencies,” Miami-Dade  police said in a statement obtained by NBC Miami. “They urge anyone with information that leads to the whereabouts of Andrew Caballeiro to contact 9-1-1.”
