William Jennings was walking on the 3300 block of Jefferson Boulevard Friday around 10:35 p.m. when he was killed.
Surveillance video shows the 35-year-old being confronted by a male suspect. The two men exchanged words before detectives say the suspect stabbed Jennings repeatedly with a knife. The suspect then walked away.
Jennings' mother, Linda Henry, has seen the surveillance video of her son's murder.
"For this guy to take my son senselessly like this, to take his life, you know, that was my one and only child," said Henry. "It was like he knew him because he didn't defend himself. I don't want retaliation on this man's life because God said don't take a life for a life. I just want him to be a man about this and turn himself in."
Jennings' wife, Tymesha, says after she and her husband returned home from a Christmas party, he left to walk to a nearby store and never returned home.
During her interview with Eyewitness News, Tymesha had her husband's bible on her lap. She says he was a godly man and a loving husband. She reflected on their wedding day three years ago.
"I just watched a video of our wedding and his mom walked in, and he was getting dressed, and he was like 'I am happy', and since he said that on his wedding video, I am happy," said Tymesha.
Authorities say Jennings is survived by his wife and 11-year-old daughter.
The suspect is described as an African American male, between 30 and 40 years old, about 5 feet and 8 inches tall, weighing about 180 pounds.
So far, there is no word on a motive.
