CINCINNATI, Ohio (WTVN) -- The FBI is searching in Ohio for a man wanted for kidnapping his son from Maryland back in 1996.

"We got a tip that he may be located somewhere in Ohio," said the FBI's Todd Lindgren. The tip did not specify where in Ohio.

Investigators recently received information about Reuben Bennett Blackwell, II and are now asking for the public’s help. Blackwell is wanted for unlawful flight to avoid prosecution in Maryland, for kidnapping his then three-year-old son Reuben Bennett Blackwell, III, who may now go by his middle name.

Blackwell is wanted for abducting his son in May 1996 and obstruction of the lawful exercise of parental custody held by the mother.  Blackwell threatened to kill his son at the time of the abduction. 

"We do consider him to be dangerous," Lindgren said.
