Authorities are Burley Garciastill 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.
