"He is now in custody being charged with aggravated robbery", Wallace said.
"He usually talked about that he became once getting married the following day so he didn't address to pay for for a wedding ceremony ring that he wished to hang and he wished to pay for the marriage ceremony venue", Trinity County Sheriff Woody Wallace talked about.
Bumpous told police that he needed the money to pay for the ring and the wedding venue.
When the fiancee saw surveillance video stills of her husband-to-be robbing the bank that police had posted on Facebook, she persuaded him to surrender to police.
The teller handed Bumpous money and he left the bank, driving around country roads and throwing out items used in the robbery, according to deputies.
Most of the stolen money has been recovered and the police thanked Heath's fiancée for her help in turning him in.
"So apparently that was what the money was for, for us to pay for him to get married tomorrow", he said.
"His picture was all on Facebook".
