It's hard to know what is more chilling about Sandra Herold's 911 call - hearing her helpless sobbing as she reveals her pet chimp is "eating" her friend's face, or the ape's frenzied screams in the background.
For an excruciating 12 minutes, Sandra is heard pleading for police to rush to her home to shoot dead Travis, the animal she had raised as her own son for the previous 14 years, reports the Daily Star.
"Tell me, what is the monkey doing?," the operator asks as Travis's harrowing, almost gleeful, wails and screeches echo down the line.
