CHARLOTTE, N.C. — WCNC NBC Charlotte has obtained two surveillance videos showing the suspects wanted in connection with the murder of Brooks' Sandwich House co-owner Scott Brooks. 

NBC Charlotte Defender Alex Shabad received the video through a police source Wednesday morning. 

Brooks was shot and killed shortly after arriving at the family-owned restaurant on December 9. According to the time stamp on the video, the suspects were at the restaurant just before 6 a.m. Detectives believe Brooks' killing stemmed from a robbery attempt. Police said Brooks was preparing to open the shop when he was confronted by an unknown suspect. 

CMPD announced Wednesday that anyone who has information about Brooks' homicide would be eligible for a reward up to $21,000. The FBI made a $10,000 contribution to the reward, as well as other local organizations. 

"The support we receive gets us through the grief," said David Brooks, Scott Brooks' brother. "It's not easy. It was my twin brother. I just hope...what we're doing today is going to help find and convict someone.

"Can't bring him back but maybe bring a little bit of justice."

A Charlotte-Mecklenburg Police spokesperson said video surveillance would be critical to solving the case, asking any homeowners or businesses in the area to come forward with anything that could provide a clue. 

Brooks and his twin brother David ran the three-generation, family owned business that was started by their father, CT, in 1973. The cash-only restaurant is known for its burgers, hot dogs and chili.

"Anyone who knows Charlotte, knows that that place is a staple of the community," Charlotte-Mecklenburg Police Department Major Dave Robinson said. "It's an iconic kind of place and a landmark."

"It hits home hard," one woman told NBC Charlotte, later adding, "It's sad what's going on in the city of Charlotte. It's like every day we lose another life to murder."

A GoFundMe memorial fund was made in honor of Scott Brooks. Proceeds will go toward funeral expenses and college funds for his son. As of January 8, $42,543 had been raised, far exceeding the $20,000 goal.
