Update: Brielle Morella turned up safe in Old City Philadelphia overnight.
Authorities are seeking the public's help in finding a Pennsauken teenager who went missing while attending a concert in Camden on Friday.
Brielle Morella, 15, was last seen with a friend outside the Susquehanna Bank Center in Camden around 4:30 p.m. Friday. She was attending a concert by rapper Wiz Khalifa when she and a friend became separated, according to the Camden County Prosecutor's Office.
Morella sent a text message to the friend around 8 p.m. Friday asking to be picked up in Camden, but her friend received no more information. Morella has not contacted anyone since, a spokesman for the prosecutor said late Saturday.
A Facebook group dedicated to finding Morella gained more than 800 followers less than two hours after it was created.
Anyone with any information on Morella's whereabouts is urged to contact the Pennsauken Police Department at 856-488-0080, ext. 2407. Information can also be emailed to firstname.lastname@example.org.
