A man on trial for a notorious Las Vegas cold case agreed to a plea deal Thursday in the death of a teenage girl.

Former boxer Willie Shannon entered an Alford plea to second degree murder. Basically, he admitted there was enough evidence to find him guilty in the killing of 18-year-old Jamey Walker in May of 1981. 

In exchange, he will avoid the death penalty.

It’s a story the I-Team has been following for nearly 35 years.

Walker was an honor student, cheerleader and homecoming queen with a bright future.

She was raped and tossed off a bridge at Lake Mead, her body was found on the rocks 45 feet below.

Last year, Jamey’s cousin told 8 News NOW that Jamey was always afraid of her next door neighbor Willie Shannon.

“Jamey was afraid of Shannon. There’s a lot of girls in the community that we grew up in that were afraid of him and think he will always be a predator and will always be a risk to any young person or young girl that’s near him,” said Gayla Walker Thornton, Walker’s cousin.

Police long suspected Shannon was the culprit, but new DNA evidence allowed them to finally charge him with the murder in 2010.

Jamey Walker’s mother Eleanor was a well-known community activist in west Las Vegas, but she died in 2013 before she was able to see justice done.

Shannon’s sentencing is scheduled for March 10.
