A 911 caller attempted to get Daffney help while she was still alive and emotionally broadcasting on Instagram Live ... but tragically, cops could not locate her before her death.
The call, obtained by TMZ Sports, reveals a man who identified himself as a friend of a friend of Daffney's trying to get police in Georgia out to the ex-wrestler on Sept. 1 before she could harm herself.
In the audio, the man can be heard saying Daffney -- real name Shannon Spruill -- was on the social media platform, appearing to be suicidal.
