Police are treating the case as a homicide.
As Texas police continue efforts to identify a little boy whose body was found on a beach, they have given the boy a name: Little Jacob.
A resident found Little Jacob’s body on a beach in Galveston on Oct. 20 and since then, investigators have been unable to find the boy’s family.
Police have not released information on how they believe the child died, but the FBI is offering a $10,000 reward for leads in the case.
The young child, who was found naked, is believed to be 3 to 5 years old. His body was not severely decomposed, according to reports.
Police said none of the tips they have received thus far have furthered their investigation, according to reports. The case is being treated as a homicide, authorities said.
"We have 37 miles of beaches here in Galveston," Police Capt. Joshua Schirard said. "Experiencing a drowning is not something that's foreign to us. Drownings, while sad, are easy. This is extremely unusual."
Police put out a sketch of Little Jacob and said he may have disappeared as early as Oct. 18.
"It's heartbreaking that no one has come forward," said FBI Assistant Special Agent Ed Michel. "We believe someone out there knows something or has seen something that could help us in this investigation."
Police also listed possible clues to help the public identify the boy’s family.
"Prior to the boy's disappearance, family members of the child may have indicated that the child caused additional stress on caregivers due to the child's health or behavioral conditions," Schirard said. “The family might have unusual interest in the investigation or seem nervous or irritable."
He added: "Someone out there knows this child's family.”
Police also said it is not clear whether the child is even from the U.S.
"At this point we're not concerned with the documented status of Little Jacob, of his parents, of his family," Schirard said. "My hope is that we don't have to call him 'Little Jacob' for long."
Authorities are putting up billboards from Texas to Kentucky to Louisiana to help solve the case, reports said.
