Knoxville, TN (WOKI) The Knox County Sheriff’s Office is investigating multiple vehicle burglaries in Knox County.

The string of vehicle burglaries occurred in Knox County in the months of September and October, some of the break-ins targeting police cars.

Knox County Sheriff Tom Spangler provided an update to media Thursday.

“Fifteen to twenty confirmed vehicle burglaries, three of those were law enforcement vehicles; two stolen vehicles, both have been recovered; seven [stolen] firearms,” listed Spangler in his address to the media.

Sheriff Spangler says two suspects, William Bruster and Zachary Jordan, have also been arrested in connection to the series of burglaries that began near the end of September.

According to Spangler, Bruster was charged with three counts of vehicle burglary and one count of violation of probation. Jordan also faces two vehicle burglary charges and a violation of probation charge, along with a charge for vandalism.

Spangler said the investigation is ongoing and “probably will be for some time” as the sheriff’s office is working to get more information from Bruster and Jordan, adding that there may be more people involved with the burglaries.

Spangler and other office representatives are urging the public to “be diligent;” make sure there are no valuables in your car and keep it locked. They also warned that the approaching holidays can mean more car break-ins.
