Authorities are continuing to search for two Lake County teenage brothers who have been missing for just under two weeks.

Wesley Charlo Jr., 17, and Xavier Charlo, 15, were last seen about 9 a.m. Jan. 12 on Butte Street in Nice, according to the Lake County Sheriff’s Office. They are believed to be on foot.

On Jan. 14, the California Highway Patrol issued a feather alert — a notification alerting the public about missing Indigenous people — that extended into lake, Napa, Mendocino and Colusa counties.

Wesley Charlo Jr. was described by authorities as 5 feet, 9 inches tall, 140 pounds, with long black hair and brown eyes. He has the tattoo of an “A” on his right shoulder, the Sheriff’s Office said in a news release. Xavier Charlo is described as 5 foot, 9 inches tall and 125 pounds with medium-length hair and brown eyes.

Authorities do not know what they were wearing when they were last seen.

The Sheriff’s Office and CHP are asking that anyone with information on the teenager’s whereabouts to call 911 or the Sheriff’s Office dispatch 707-263-2690.
