Police in North Carolina are seeking help to locate a pregnant 12 year old girl who went missing September 24.

Keara Lasha Hess, who was 9 months pregnant at the time of her disappearance, her 11 year old sister Sierra Nicole Hess, and their step father Matthew Hess disappeared without warning Thursday.

No amber alert has been issued because the stepfather is the legal guardian, so although the girls are missing, they haven’t been abducted as such. Keara though was suppose to have seen a doctor the day she disappeared for treatment related to her pregnancy.

Matthew Hess was driving a forest green 1993 Ford Explorer with the license plate number YTE-8014. According to local media, “the back passenger window is broken and covered with Plexiglass and duct-taped in place.”
