The search for a missing 14-year-old Virginia girl believed to have been abducted from her home has intensified after law enforcement joined forces with the FBI.

Isabel Shae Hicks disappeared around 1 a.m. on October 21 from her home in Bumpass, around 40 miles northwest of Richmond, Virginia. Investigators said she may have been abducted by 33-year-old Bruce William Lynch.

Investigators issued an Amber Alert for the “endangered” teen this past Friday, three days after the FBI joined the investigation. A felony warrant also was issued for Lynch.

Lynch, also of Bumpass, was believed to be “armed and dangerous” with a 9MM handgun in his possession.

Authorities say Lynch is driving a light blue, almost silver looking, 2003 Toyota Matrix with Virginia license plate VEM-9071.

“Information received appears they may be traveling out of state and staying in areas where they could camp,” investigators said.

Hicks was described as a 4-feet-11-inches tall, and 120 pounds with blonde hair and blue eyes. She had a birthmark on the inside of her right leg and had both ears pierced, investigators said.

Lynch was described as a Caucasian man, 5-feet-10-inches tall and weighing 190 pounds. He had brown hair, brown eyes and a brown beard. He had cross tattoos on both his upper arms and a tattoo of “Bruce” at the top of his back.

Anyone with information is asked to call 911.
