A Northern California canal near the location where a little boy was kidnapped earlier this week remains the main focus of investigators Friday, three days after the child was taken from his grandmother's arms.
Three vehicles have beeen removed from an area of the canal where a man said he saw a car that fit the description of the man who took the boy. None are connected to the case.
A fourth object, possibly a car, was located about a mile south of the original location late Friday and police may fish it out of the canal either late Friday or early Saturday.
All of the effort is in hopes of finding 4-year-old Juliani Cardenas, and the man suspected of kidnapping him, 27-year-old Jose Esteban Rodriguez.
Authorities said Cardenas was abducted Tuesday from Patterson, in Stanislaus County.
Police have been looking for Rodriguez car, a silver 2003 Toyota Corolla.
Juliani has been the subject of a statewide Amber Alert. Drivers across California have been told to look for license plate 6HBW445. Officers said the car has oversized aluminum wheels and may have one spare tire on the front passenger side.
The sheriff said the worker who spotted a car roll into the canal shortly after the kidnapping now believes that he saw a man and child sitting in that car.
"There are no other credible leads, ladies and gentlemen, that are taking us in a different direction," Adam Christianson told KCRA TV.
He said other leads have been unfounded.
Police said Rodriguez is 5 feet, 9 inches tall and weighs about 180 pounds. He was last seen wearing a white and black shirt with checkered shorts and a beanie.
The sheriff said he's talking with the California Highway Patrol about how long the Amber Alert signs can stay active.
