MONTGOMERY, Alabama -- Just four weeks before being charged with the homicide of the Taco Bell night manager he worked with, Renauldous Chisholm had expressed his fears on his Instagram account.

“I swear my only fear is failing in life and not being everything I know I can be,” the 19-year-old wrote in the caption of a photo, which appears to be a double image of him standing in the restaurant.

The words are poignant now as he potentially faces a life sentence in the beating and shooting death of Vettia Roche, 43, early Monday morning during the commission of a robbery.

Roche’s body was found Monday morning at around 7:30 a.m. behind the Atlanta Highway restaurant where she worked, Montgomery police released. Roche had been beaten with a car jack and shot multiple times during a robbery early that morning.

His friend and former co-worker, Kenneth Temple, also is charged with capital murder in connection with the crime.

Both teenagers appeared happy and had a large following on social media. Many of the images on their Instagram accounts were pictures of them together or taken inside the Atlanta Highway Taco Bell where they worked.

Many of their followers and others have taken to social media over the last few days to express their sadness and asking why these two men could have possibly committed murder.
