(CNN) — Investigators searching for a missing 8-month-old boy began an intensive excavation and search effort Tuesday at a Texas landfill.
Gabriel Johnson was last seen in San Antonio, Texas, with his mother, Elizabeth Johnson.
“Let me say this, that we do remain hopeful that baby Gabriel is alive,” William McManus, chief of the San Antonio Police Department, said at a news conference at the landfill.
We are, however, conducting both a missing persons investigation as well as a homicide investigation,” he said, adding that aspects surrounding Gabriel Johnson’s disappearance involve elements of a possible homicide.
