NORTH CONWAY, N.H. (CBS) --- There were prayers for Abby Hernandez more than two weeks after she vanished without a trace.
The 15-year-old was last seen on October 9, leaving her high school.
Hundreds turned out Saturday night to offer support for Abby's mother.
"There are people that you interact with on a daily basis that may have changed their behavior from that day forward. We ask you to please come out with any tips and information," Zenya Hernandez said.
The FBI says they do not think Hernandez left on her own.
