Nachida Keota Chandara was 15 when she was last seen by her family at their Phoenix home near South 67th Avenue and West Lower Buckeye Road on March 14, 2007. Authorities later placed her in Detroit, Michigan, on May 17, 2007, where she was using the name Lisa Tran. That Detroit sighting is the last confirmed point on her timeline.

Of Laotian descent and known to friends and family as Nacho, Chila, Sonny or Na Na, she was described as five feet two inches tall, about 120 pounds, with black hair, brown eyes, multiple ear piercings, a scar on her left forearm and a tattoo of three dots on her right hand. Investigators say she may also have used names including Lisa Lang Tran, Lisa Marie Tran and Sonny Somsamouth. Reports suggest she might later have traveled to Seattle or Miami and that she may have been with an adult man or woman, but those movements are not confirmed.

No vehicle, later communication with her family, arrest or public criminal charge has been announced. Her family provided DNA reference samples and an age-progressed image was later issued to aid identification. If anyone knew Nachida, saw her after May 2007, or has information about the name Lisa Tran in Detroit, please come forward.
