Family and friends held a candlelight vigil to remember a father shot and killed at a west Nashville restaurant.

Robert Saine, age 36, was pronounced dead at the hospital after police said an argument led to a shooting outside the Waffle House on White Bridge Pike.

The shooting happened around 2:30 a.m. Sunday. The gunmen were not caught as of Sunday night.

Those close to Saine described him as someone who was always fun and energetic. He was also part of a Nashville car club called Nashville INC.

"He just liked being part of something positive," Kelly Beavers, a friend, told NewsChannel 5. "He was a breath of fresh air to our club."

"He was somebody, he was a great father, a great husband. He was just a good person," Beavers tearfully said. "He was always happy."
