Surrounded by family and friends, this mother is determined to get her daughter home.

“She’s gotta come home. We love you Aviana. We love you,” Scarlett said. She says her 17-year-old daughter named Aviana Weaver went missing after going to a friend’s house to do homework. That was on September 12.

She’s now working with police in both New Jersey and Philadelphia.

“The biggest concern we have right now is we believe she’s in human trafficking, we believe she is being held against her will,” Scarlett said.

The teenager went missing from Mount Holly, New Jersey, however, her phone was pinged 23 miles away in West Philadelphia.

Eyewitness News showed the missing girl’s picture to those in the neighborhood, where her cell phone was last pinged. Police say it was in a building on the 200 block of South 49th Street.
