A former Foothill High School student who returned to the Bay Area for college after her family moved from Pleasanton to North Carolina has been reported missing in San Francisco and is considered at-risk, according to authorities.

Sydney "Syd" West, 19, has not made contact with family or friends since last Tuesday (Sept. 29), and her last known location is believed to be San Francisco near Crissy Field on Wednesday morning, according to the Orange County (N.C.) Sheriff's Office which has been in contact with the San Francisco Police Department.

"We are asking anyone who has any information about our daughter Sydney to please contact the investigators. We are anxious to have our daughter found safe and brought home," West's parents said in a statement released through the sheriff's office on Monday.

The Pleasanton Unified School District confirmed West attended Foothill during her freshman and sophomore years before her family moved to North Carolina. She is listed now as a resident of Chapel Hill, N.C.

Orange County Sheriff's officials said West had been living in the Bay Area since late August, stating that she was "until recently" a student at University of California at Berkeley and since had been residing with friends in San Francisco.

West is considered to be at-risk due to depression, according to SFPD. A family member reported her missing on Friday after she had not been heard from for nearly three days.

West is described as white, standing 5-foot-10 and weighing 130-135 pounds, with blue eyes and light-brown hair usually worn in a ponytail. She was likely wearing dark shorts, slip-on Vans shoes and carrying a black backpack, according to investigators.

The case is being investigated by the missing persons section of the SFPD special victims unit.

Anyone with information on West's disappearance can contact SFPD at 415-575-4444, or text a tip to TIP411 (847411) with "SFPD" at the start of the text message. Those with connections to West in North Carolina can also contact her hometown sheriff's office at 919-245-2909.
