Affidavit reveals circumstances behind Valentine’s Day Murder

CHATTANOOGA, Tenn. (WDEF) – A suspect is in custody after being charged with criminal homicide in Chattanooga on Valentine’s Day.

Police responded to the Cypress Hill Courts yesterday afternoon around 4:30 p.m. to a report of shots fired.

This has left a man dead.

According to the police affidavit, the incident began far before yesterday afternoon.

Chattanooga Police say 33-year-old Legraine Poston, Jr. is their suspect in yesterday’s homicide in Cypress Hill Court.

Two people were shot, a man and a woman.

Police say 26 year old Keyshawn Kidd was declared deceased upon arrival at the hospital, and the female victim arrived on her own and was treated for her injuries.

We have learned more about the circumstances according to an affidavit obtained through the Hamilton County Courthouse.

In the affidavit, Police say they were told the incident began two days earlier on Sunday.

On that day according to victim testimony, Poston was involved in a domestic altercation with his girlfriend.

The female victim states that they were called several inappropriate names during this incident.

This set the stage for yesterday’s incident.

Chattanooga Police Executive Harry Sommers said the shooting stemmed, “Ostensibly coming from a dispute or maybe a domestic issue between two people who knew one another.”

Two days later on Valentine’s Day according to the affidavit, Kidd approached Poston and asked him to apologize for the domestic incident on Sunday,

This is when the female victim states that Poston and Kidd began to fight due to Poston’s refusal to apologize.

They say that Kidd was trying to defend himself when Poston retrieved a firearm from his vehicle.

They say he then shot Kidd and herself, and then fled.

The affidavit mentions that Police confirmed the victim’s story via video footage from a nearby camera, showing the altercation that led to the shooting.

Video according to the affidavit shows Poston shooting at both victims while they were attempting to run away.

It then shows him fleeing the scene in a gray Honda Pilot S-U-V according to the affidavit.

Sommers said that, “We put that information out on a Be on the Lookout throughout the Law Enforcement Community.”

Nick: According to the affidavit, the Tennessee Highway Patrol arrested Poston on I-24 westbound in Marion County between Martin Springs and Monteagle.

Sommers said, “It was so quick in being resolved, but unfortunately a tragedy in our community.”

The affidavit states that Poston is a convicted felon for Attempted Aggravated Battery in 2011 and Aggravated Robbery in 2014.

This prohibited him from owning firearms.

He is being charged with criminal homicide and attempted first degree murder among other charges.

He is currently being held in the Hamilton County Jail on $350,000 bond.
