Bryan Barnes told The Baltimore Sun on Sunday he doubts 16-year-old Phylicia Barnes, who was visiting relatives in Baltimore when she disappeared in December, would have decided to go to an area about 40 miles away without telling anyone.

Bryan Barnes also said he’s hopeful authorities will make an arrest soon in his half-sister’s death.

Phylicia Barnes’ body was found Wednesday near the Conowingo Dam on the Susquehanna River in northeast Maryland. The body of an unidentified male was also found. Bryan Barnes says the family doesn’t know of anyone missing who might be linked to Phylicia Barnes.
