OKLAHOMA CITY - Jack McClung, 79, was somewhat of a famous Oklahoman.
His life ended Sunday afternoon as he was walking across N.W. 23rd street between Meridian and Portland and a speeding driver hit and killed him, then took off.
McClung was the founder of Blue Stuff, an ointment made from emu oil that he claimed relieved severe pain.
His sales hit more than $80 million back in 2002, but then he was sued by the Federal Trade Commission for making unsubstantiated claims about his product.
"He was just crossing the street. He had a bag of groceries, just crossing the street," said eyewitness, Charles Combs.
Combs watched in horror as the car slammed into McClung and then just drove away.
"I look up and I see the car hit the old man. The old man goes up in the air and kind of lands back on the car. And the red car like backs up and just goes around the old guy. Just goes around him, just took off and goes around the guy," said Combs.
Oklahoma City police rushed to the scene and blocked off the area.
Police say McClung had just left Braum's when he was hit by the car that was traveling eastbound at a high rate of speed.
McClung's groceries were scattered all over the roadway.
In a Great State story back in 2011, NewsChannel 4's Galen Culver detailed how McClung had just spent a year in Mexico and found a new formula for his pain fighting cream.
At age 77, he was back at it, taking orders on a new website.
But his ideas and his life were taken from him on Sunday by a driver who seemingly didn't even look back.
"Never seen nothing like this in my life. It really freaked me out. It was just shocking like you could just actually leave someone in the street like that," said Combs.
The suspect's vehicle is described as a black 4 door 2006-2008 Mazda 6 with a red bumper, red grill and red stripe down the side.
It should have heavy damage to the driver side windshield and a missing driver side window.
