Justin Fernando Merritt, 34, is being held at the Wake County Jail without bond.
Murder suspect makes first court appearance
He appeared in court earlier this week on charges of larceny of a motor vehicle, robbery with a dangerous weapon and possession of a firearm by a felon.
Those charges were in connection to the theft of Banks' SUV -- a 2011 silver Range Rover.
The two apparently met through Craigslist when Banks went to meet Merritt in Cameron Village on Saturday to sell his car.
Banks was reported missing hours later by his friends.
The Range Rover was found Monday afternoon in Danville, Virginia. On Tuesday, Merritt, was arrested and charged in the theft.
On Thursday, a body believed to be that of Banks was also found in Virginia.
Updated court records showed Merritt was then also charged with murder.

Friends told ABC11 on Friday, if nothing else, they're happy someone was caught.
"Hopefully, it will bring closure and he will not see the light of day here. In my heart, I hope that," said Holly Haygood.
She grew up with Banks near Gastonia.
"Andy was the definition of fun," she said. "He was always the life of the party. He was never in an ill mood. He will really be missed and is cherished with everyone that he came in contact with"
Friends have started a remembrance page on Facebook and 4,000 people have offered support.
One person reflected on how Banks was "goofy and had quirks, which made us love him more."
Another person said she was "heartbroken."
Authorities are not sharing how Banks was killed or in which state it happened.
