Federal immigration agents have joined the search for the suspect in a fatal hit-and-run that left a Knoxville woman dead last week.

The U.S. Immigration and Customs Enforcement Agency is assisting in the search for 54-year-old Juan Francisco, ICE spokesman Bryan Cox confirmed Tuesday.

Knoxville police have identified Francisco as the suspect who struck and killed Debbie Burgess, 52, as she walked along Pleasant Ridge Road near the Custom Foods of America plant June 8.

Authorities have active arrest warrants for Francisco on charges of vehicular homicide and leaving the scene of an accident.

The suspect's local criminal history includes a DUI conviction in 2017.

He also was convicted of theft in 2002 for forging another man's name on a Tennessee driver's license and Social Security card while working a local landscaping company, according to an arrest warrant. The warrant identifies Francisco as an undocumented immigrant.

Cox said Wednesday that Francisco's immigration status has not changed in the years since.

In 2004, Francisco was charged with driving without a valid license. That arrest warrant notes he had a Guatemala driver's license at the time, but no permit to drive in the U.S. The violation was retired in 2010.

Anyone with information on Francisco's whereabouts is asked to call the Knoxville Police Department's crime hotline at 865-215-7212.
