The colleagues of an Air Force veteran who was assaulted and killed over the weekend are asking for the community's help to raise money.

Around 2 a.m. Sunday, 33-year-old Marques Johnson was walking with his wife on East 6th street when they were approached by two men. Police say that the two groups exchanged words and Johnson walked away but one of the men threw an object at him to get his attention.

When Johnson turned around, police say that he got punched in the face.

The men took off and Johnson was taken to a hospital where he died. Police say that Johnson’s death was likely caused by his head hitting the pavement.

KENS 5 talked to Johnson's manager, David Yelverton at Convergint Technologies. He said that Johnson started at the company eight months ago and was someone who led by example.

"Having integrity, communicating, living a balanced life. That was not only apparent at work. It was also in his personal life," Yelverton said.

Johnson's wife also works at the company. Yelverton said that the couple got married 18 months ago and purchased a new home. He noted that people at work decided to start an online fundraiser to help with the family's bills and funeral expenses.

"We're a company that believes in caring about our colleagues," Yelverton said. "She's going to come through this like we all will through prayer, through friendship, through support of her family, friends, Marques' family. We're all here for her."

Austin police said that the man who hit Johnson is a black man in his 20s. They describe him as between 5’10 and 6 feet tall. They say that he has short, curly black hair, light-colored eyes and a beard. The man was last seen wearing a light-colored shirt with blue jeans.

Austin police say that there were witnesses who reported seeing people taking cell phone video of the assault on Sunday. They urge those individuals to contact them at 512-477-3588 or call Crime Stoppers at 512-472-TIPS (8477).
