According to officials, deputies responded to the wreck on Sunday, May 7 along Armstrong Valley Road, where they found Detective Jacob Beu critically injured. He was brought to Ascension St. Thomas Rutherford, where he later died.

“Detective Beu was a valued detective in the Narcotics Division,” Sheriff Mike Fitzhugh said. “We send our sympathy to his family and his Sheriff’s Office family in his death.”

Authorities said Beu was a veteran sheriff’s office deputy who was promoted to patrol corporal in 2021 before being promoted to narcotics detective in 2022.

Beu reportedly served as a member of the SWAT Team, with Beu and the rest of the team being honored as Officer of the Month in August 2021 for responding to the devastating floods in Waverly and Humphreys County.

The sheriff’s office said Beu was also honored by the Mothers Against Drunk Driving in 2018 for making numerous arrests of drunk drivers.

In addition to his law enforcement career, Beu served as a U.S. Marine, officials said.

Funeral services are pending, according to authorities.

The sheriff’s office also posted a video on social media of Rutherford County first responders and Tennessee Highway Patrol troopers joining Rutherford County deputies Sunday afternoon to transport the detective’s body to the state Medical Examiner’s Office in Nashville.

The La Vergne Fire Department also honored Beu by draping an American flag over Interstate 24, along the procession’s route.

Numerous law enforcement, emergency response, and government officials have extended their condolences to Beu’s coworkers and family. That includes the Rutherford County government, the Murfreesboro Fire Rescue Department, the Middle Tennessee State University Police Department, the Mt. Juliet Police Department, Clay County Emergency Management, the Hickman County Sheriff’s Office, the Dickson County Sheriff’s Office, the Hendersonville Police Department, Monroe Fire and Rescue, and the Sumner County Sheriff’s Office.
