Authorities are still searching for two children they say were abducted by their parents two weeks ago in Los Angeles during a supervised visit.

Siblings Wyman Bryant, 4, and Willow Bryant, 2, were last seen around 3:10 p.m. on Aug. 14, according to the Los Angeles County Sheriff's Department.

The children were with their parents, Tiffany Bryant and David James, for a "supervised visit" when “against child custody orders, the parents took the children and left the location,” authorities said in Facebook post requesting the public's help in finding them.

“There is concern for their well-being,” the sheriff’s office added.

On Wednesday afternoon, a detective working the case said authorities are still actively looking for the children. Investigators are working with other law enforcement agencies to find them.

According to the detective, the children may be in California but their parents are known to travel to other states, including Oregon, New Mexico, Arizona and Georgia.

Description of the missing children

Willow, the couple’s daughter, is 2-feet-tall and weighs 28 pounds. She has brown eyes and blonde hair and was last seen wearing a blue shirt, pink and white shorts and pink and white Nikes. 

Her older brother, Wyman, is 2-feet-tall, weighs 35 pounds and has blonde hair and blue eyes. He was last seen wearing a blue shirt and gray shorts.

The adults and children left in a brown Buick Enclave SUV. The vehicle has no front plates and blue rear paper plates.
