Caleb McGrady, 26, of Tyler, Texas, was one of two people killed on December 27, 2018, as they were leaving a house party in the 2300 block of Ridgewood Drive, just off the east side of Loop 323. Krista Newman, 25, of Frankston, Texas, also died in the incident; authorities later treated both deaths as a double homicide.

The suspect named in the case is 26-year-old Harvey Louis Martin of Whitehouse, Texas. He turned himself in to the Tyler Police Department, led officers to the firearm used in the shooting and confessed. A psychological evaluation later found him competent to stand trial. In April 2021 Martin pleaded guilty; capital murder charges were reduced to first-degree murder under a plea agreement, and he was sentenced to life in prison with no possibility of parole for at least 30 years.

What details about that night or the people involved have not been discussed that might help explain how the violence started?
