Walking Dead actor Moses J Moseley's cause of death 'could not be determined' according to his death certificate.
The 31-year-old actor was discovered unresponsive in his car on January 26 in Stockbridge with a gun in his lap.
Moses appeared on the Walking Dead for three years from 2012 to 2015 as the unforgettable, Mike.
A coroner's report since obtained by TMZ, lists the actor's cause of death as 'gunshot would to be head' - but it is still uncertain whether the fatal shot was accidental or intentional.
The report still leaves uncertainty over whether the actor took his own life, or accidentally shot the gun during a tragic mistake.
At the time of his death, a family member of Moses told TMZ the star was found in the Hudson Bridge area of Stockbridge, Georgia.
They said they hadn't heard from Moses in several days and a call around all local hospitals didn't provide any further detail of his whereabouts.
After filing a missing person's report after a number of days, the actor's family are believed to have contacted OnStar, which tracked his car and led them to his body.
His manager, Tabatha Minchew released a statement saying: "He was loved by everyone who met him. Such a bright light in everyone's eyes."
Moses starred on The Walking Dead between 2012 and 2015 as one of Michonne's zombies that followed the character around.
He also featured on other hit shows such as HBO's Watchmen, while on the big screen he played a role in 2013 film The Hunger Games: Catching Fire.
The Walking Dead's official Twitter page also posted a pic of Moses alongside the caption: "Our thoughts and prayers are with our #TWDFamily member Moses J Moseley."s
