HATTIESBURG, Miss (THN News) - In Day 3 of the Donivan Recordings, for the first time, we are hearing Lamar County Sheriff's Office admit that Andrew David Cook, then a 23 year old white male suspect, killed Donivan Barnes.
In the new audio, Lamar County Sheriff's Office Lead Investigator John Brown tells Donivan Barnes family he was 100% sure that suspect Andrew David Cook killed Donivan Barnes based on the evidence.
"Everything lines up and is consistent with that fact. And we know the gentleman, the guy, hit something. Yes I'm 100% I know for a fact it was Donvian," said Lead Investigator Brown.
However, two years at the grand jury hearing, he did not say the same thing. His story somehow changed. We do not know at this time what he told the grand jury in March 2025.
Legal experts who've heard the new audio are in shock that the District Attorney's Office has dismissed the case with one legal expert calling it "a miscarriage of justice."
What we do know is that if a sworn law enforcement official, let alone the lead investigator in a case, had told the grand jury he was 100% sure that suspect Andrew David Cook had killed Donvian Barnes, based on the evidence, as he told Donivan's family, at the very least, Andrew would have been indicted and more than likely in prison given Lamar County Conviction rate.
Donivan's case was officially dismissed for lack of evidence. Lead Investigator John Brown was the District Attorney's main witness at the grand jury, along with the suspect Andrew David Cook and his mother, Dr. Kimberly Walker Yawn.
