KNOXVILLE, Tenn. (WOKI / WVLT) — Attorneys representing the family of Lisa Edwards, a woman who died while in Knoxville Police Department custody in 2023, are asking a federal judge to exclude testimony from a key medical examiner in the ongoing civil case.
In a filing dated June 18, the family’s legal team argues that the testimony of Dr. Christopher Lochmuller, one of Knox County’s chief deputy medical examiners, should be thrown out. The motion claims his conclusions are not supported by sufficient facts or reliable methodology and could unfairly influence a jury.
The filing specifically challenges Lochmuller’s opinion that Edwards’ pre-existing medical conditions contributed to her death. Attorneys also dispute his assertion that a lack of post-discharge medical care did not affect her condition. Additionally, Lochmuller previously testified that the actions of the officers involved did not cause Edwards’ death — a conclusion the family strongly contests.
Lisa Edwards died in February 2023 after an encounter with Knoxville police officers at Fort Sanders Regional Medical Center. Officers were called after Edwards refused to leave the hospital following her discharge, telling staff she was in pain and feared she might suffer a stroke.
During the encounter, officers — identified as Sergeant Brandon Wardlaw, Officer Adam Barnett, Officer Timothy Distasio, and transportation officer Danny Dugan — took Edwards into custody. She later died from a stroke while being transported to the Knox County Detention Facility.
The case previously drew public attention after the release of body camera footage in which Edwards can be heard expressing distress and warning, “I am going to die.”
The Knox County District Attorney’s Office later determined that Edwards died from a stroke and declined to file criminal charges against the officers involved.
The current legal proceedings are part of a federal civil case brought by Edwards’ family. The motion to exclude Lochmuller’s testimony is one of several pretrial disputes that could shape what evidence is presented if the case goes before a jury.
No ruling has yet been issued on the family’s request.
