Wright was a star basketball player at the University of Memphis. He played in the NBA, including a stint with the Memphis Grizzlies.

Lorenzen Wright was last seen on July 18, 2010.

In the early morning hours of July 19, Wright called 911 from his cellphone. A Germantown dispatcher heard someone curse, followed by nearly a dozen gunshots.

Nine days later, Lorenzen Wright’s body was found in a southeast Memphis field.

When Wright’s body was found, he was still wearing expensive jewelry. Police looked into Wright’s dealings with associates in Atlanta regarding recent auto sales. Authorities even questioned his friends and even his wife, Sherra.
