Authorities say a Tennessee deputy was deliberately lured into an ambush after a woman allegedly fired a gun at a motel, called 911 to report it, and then waited for law enforcement to respond before shooting him to death.

The Tennessee Bureau of Investigation announced that 44-year-old Khristi Cunningham has been charged with first-degree murder in the killing of Derrick Bonham, a 37-year-old deputy with the Weakley County Sheriff’s Office.

The violence unfolded during the early morning hours of Jan. 30. Around 3 a.m., the Martin Police Department contacted the sheriff’s office seeking assistance with a reported shooting at the Days Inn on University Street in Martin, a small city in northwest Tennessee.

According to court documents cited by regional media, investigators believe Cunningham herself fired a shot at the motel and then called 911 to report it. Authorities say she did not stay at the scene. Instead, she allegedly drove roughly a mile away to a Pocket’s convenience store, positioning herself to observe the law enforcement response.

Court records indicate Cunningham continued calling 911 and hanging up. At one point, a dispatcher reportedly told Deputy Bonham that she believed the reporting party might be at the nearby convenience store.

The TBI said Bonham was checking a gas station for witnesses just after 3 a.m. when he encountered Cunningham, who was allegedly on the phone with 911 at the time he pulled up. What happened next, investigators say, was captured in part on the deputy’s own body camera.

“For reasons still under investigation, Cunningham brandished a weapon and shot the deputy,” the TBI said. Investigators allege she then shot Bonham three more times while he was on the ground. Authorities also say she fired multiple shots at other officers who responded to the scene.

Officers with the Martin Police Department were able to take Cunningham into custody. Bonham was rushed to a local hospital, where he was pronounced dead.

Weakley County Sheriff Terry McDade called the shooting a “great tragedy,” describing Bonham as kind, quiet, and humble. Bonham was a husband and the father of three children.

“I hope the person responsible doesn’t breathe our air anymore,” McDade said, according to WEWS. “If that offends somebody, I’m offended that they’re offended.”
