LOUISA COUNTY, Va. (WRIC) — The family of Isabel Hicks, a missing 14-year-old from Louisa County, spoke at a press conference Thursday with members of the FBI and county authorities by their side. Hicks’ brother and mother pleaded for the missing teen’s safe return.

Investigators believe Hicks could be with her mother’s ex-boyfriend, identified as 33-year-old Bruce Lynch, but would not confirm whether she went voluntarily or not. She was last seen Monday morning.

Hicks is described as 4-feet-11-inches tall, weighing roughly 120 pounds with blonde hair and blue eyes, authorities said.

The FBI said it is believed Isabel and Lynch may be staying in wooded areas “conducive to camping.”

Lynch, described by police as 5-feet-10-inches, weighing 190 pounds with brown hair, brown eyes, and a beard, is believed to be driving a silver or blue Toyota Matrix with Virginia tags, similar to the one pictured below.

Lynch should be considered armed and potentially dangerous, the Louisa County Sheriff’s Office said. Deputies remind locals to contact authorities and do not approach if either Lynch or Hicks are spotted.

The brief joint press conference on Thursday was held in the Louisa County Public Meeting Room in the Sheriff’s Office. FBI, state police and local authorities were in attendance.

“Isabel, I love you and I want you to come home and just let me know if you’re okay,” pleaded Cortney Lewis, Isabel’s mother.

“I just want to say that we miss you very much and we want you to come home. Please just let us know that you’re safe however you can,” said Isabel’s brother Blake Saylor.

“I’m still your big brother and I love you forever, I just need my best friend back.”

Acting Assistant Special Agent Dave Johnson, with Richmond FBI, said their “office, including agents, analysts, and other professional support personnel, have been working non-stop with the sheriff’s office, hand in hand, since the initial stages of the investigation earlier this week.”

“No bit of information is insignificant in this investigation.”

The Louisa County Sheriff’s Office said they won’t stop looking until Isabel returns home safely.

“The entire community is concerned about Isabel and we’d like to see her come home,” said Major Donald Lowe. “She’s loved and everybody’s worried about her.”

Anyone with information on Isabel’s whereabouts is asked to contact the Louisa County Sheriff’s Office at (540)967-1234 or Louisa Crime Solvers at 800-346-1466. Call the Richmond Division of the FBI at 804-261-1044 with information that may lead to the location and safe return of Isabel Hicks.
