Miami-Dade Police are seeking a father and his one-week-old child after a triple homicide that left three women dead at the infant's home. Authorities believe that the father, Ernesto Caballeiro, abducted his newborn son, Andrew Caballeiro, from the home where the women were found sometime after they were gunned down Tuesday.

An Amber Alert is in effect for Andrew Caballeiro. Ernesto Caballeiro is listed in the Alert as the abductor.

Police say they are believed to be traveling in a white van marked with a decal for “Nesty School Services,” a company that provides transportation for school children which Caballeiro founded, and another reading “Caution: Transporting Children.”

"Fearing for his well being we’re asking for assistance in the community to locate him and his newborn infant child," Miami-Dade Police Detective Lee Cowart said. "He's not at his residence and we’re attempting to locate him. We need the press and the community’s help and assistance in locating him."

Ernesto Caballeiro is described as 5-foot 7 and 240 pounds, with brown hair and black hair.

The three women were found dead from gunshot wounds by a family member conducting a welfare check. This relative called the police at around 4:30 p.m. The identities of these women and their exact relationships with the father and child have not been released by authorities. The child is believed to be related to at least one of the women.

Miami-Dade Police ask any individuals with information about the Caballeiros to call (305) 471-2400.
