Family and friends held a prayer vigil Thursday night for a Chicago high school girl who has been missing for nearly a week.

Community members gathered in the Bridgeport neighborhood to pray for Estefania Herrera. The 18-year-old is a senior at Mother McAuley Liberal Arts High School in Mount Greenwood.

Her family said she vanished on Friday on her way to a swim meet.

"I believe the meet was going to be in Tinley Park; never made it there. She did get on, she swiped her Ventra card on the Archer/Pulaski bus, Pulaski bus going south, and that was the last trace," said her aunt, Karen Forbes.

She is described as 5 feet 4 inches tall, weighing 200 pounds, with brown eyes and hair, and with a light brown complexion. She was last seen wearing a black and white checkered fleece top and jeans. She was also carrying a red backpack and a blue backpack.

Chicago police are asking anyone with information on her whereabouts to contact Area 1 SVU at 312-747-8380 or dial 911.
