La Vergne police said the investigation began after officers learned a Williamson County court had issued an order of protection against the person. Officers were initially unable to locate the resident to serve the order. As detectives continued investigating, they monitored publicly available online statements and said the threats became increasingly specific.

Police said the statements first included general threats toward family members and other people in Tennessee, then named Lee, Trimble and public locations, including places of worship. The department said the increased specificity raised concern that the threats could lead to violence and prompted officers to locate the resident.

The arrest followed a brief struggle, police said. One officer and two detectives suffered minor injuries and declined medical treatment. The resident was taken for mental health observation and evaluation, according to police.

Investigators obtained a felony charge of threat of mass violence and a misdemeanor charge of resisting arrest. The department did not identify the person in its public account.

The investigation involved the FBI, Bureau of Alcohol, Tobacco, Firearms and Explosives, Tennessee Bureau of Investigation, Tennessee Department of Safety and Homeland Security, Williamson County Sheriff’s Office, Rutherford County Sheriff’s Office and Murfreesboro Police Department.

La Vergne police urged anyone who sees or hears something that could indicate a threat to contact law enforcement. The charges are allegations; the available information does not detail the next court date or the status of the order of protection.
