Bonnie Briscoe could barely hold back the tears when talking about her niece, Phylicia Barnes.

The Monroe, North Carolina teen disappeared late last December, while visiting relatives in Baltimore during the Christmas holidays.

Briscoe and other members of Barnes’ family in Baltimore were among hundreds of volunteers and law enforcement officials who took part in a massive daylong search on Saturday, which also spanned two Maryland counties. It ended with no concrete clues about Barnes’ whereabouts, who has been missing now some four months; her 17th birthday was in January.
