Man accused of shooting Deputy McCowan sues for excessive force
BLOUNT COUNTY, Tenn. (WATE) — Kenneth DeHart, the man accused of shooting and killing Blount County Sheriff's Deputy Greg McCowan, is suing Blount County and the Blount County Sheriff's Office for excessive force that led to injuries.
DeHart is accused of killing McCowan on February 8, 2024 during a traffic stop. He was taken into custody a few days later. His trial is set for 2026.

According to the lawsuit, Mr. DeHart was polite and cooperative after being pulled over for a driving infraction. The officer said she smelled marijuana coming from DeHart's vehicle and called for backup. When the officers, including McCowen, asked DeHart to leave the vehicle, he told them that he didn't consent to a search, asking them to bring a drug dog, the lawsuit says.
'The officers refused to call for a drug dog, and instead quickly escalated the situation,' according to the lawsuit. 'Rather than following appropriate procedures and practices, they fired a Taser at Mr. DeHart four separate times, while simultaneously using physical force to try to remove him from the vehicle.'
DeHart begged the officers to stop and feared for his life, according to the lawsuit. The documents allege the tasing was unnecessary and unprovoked and that it caused significant, and possibly permanent, brain injuries. According to the lawsuit documents, when law enforcement personnel later searched the vehicle, they did not report recovering any marijuana.
The documents continue, 'As the fourth Tasing was ongoing, as Mr. DeHart continued to fear for his life and continued to experience extreme pain as well as disorientation as a result of the electrocution, an altercation ensued in which shots were fired, hitting both officers. Tragically, Officer McCowan died as a result of his injuries.'
It adds, 'Mr. DeHart did not plan or intend to hurt either officer and, like everyone else, is deeply saddened by the terrible outcome. Notwithstanding those facts, Mr. DeHart was a victim of the officers' improper use of excessive force, which violated the law and his constitutional rights.'

The documents also allege that officers used excessive force against him during his arrest on February 13, causing another head injury and other injuries.

Attorney: Ex-wife of Rex Heuermann putting on a show in documentary
(NewsNation) — Asa Ellerup, the ex-wife of accused Gilgo Beach serial killer Rex Heuermann, has defended his innocence in a new documentary released on streaming platform Peacock. In 'The Gilgo Beach Killer: House of Secrets,' a three-part documentary, Ellerup is a central figure along with her and Heuermann's daughter, Victoria. Ellerup referred to Heuermann as 'her hero' despite the pair divorcing shortly after his arrest two years ago, and that she had 'fallen in love with him all over again.' Victoria Heuermann, on the other hand, has said she believes her father is 'most likely' the Gilgo Beach serial killer. Authorities believe they spotted ex-soldier Travis Decker, who is wanted in deaths of 3 daughters John Ray, the attorney for the family of victim Shannan Gilbert, said Ellerup's statements are all about posturing herself to show she had no involvement in the killings. 'This is all for show, and she's being paid a lot of money to put on a show,' Ray said. 'She and her daughter are doing very well at that. This is all fake and her statements are informed by that fakery.' Heuermann is accused of killing a total of seven women, whose bodies were among several found on Long Island, New York. He has pleaded not guilty to all charges. Heuermann is due back in court June 17 as a judge continues to weigh whether to allow key DNA evidence into the trial. Copyright 2025 Nexstar Media, Inc.

'Very similar. Exactly, to be honest with you. Stamped with the serial number, imprinted with the Glock 19 on the slide.

The one that was seized by police was in the hands of a teenager. One of them allegedly searched the victims' pockets and asked the value of the victims' belongings.
