Sherra Wright, the ex-wife of Lorenzen Wright, was arrested in California on Friday in connection with the former NBA player's 2010 death.
Zach Crenshaw of WHBQ passed along the news and noted Deborah Marion, the mother of the 1996 first-round draft pick, said police told her Sherra will be charged with murder.
Memphis Police confirmed Saturday she faces a murder charge in the case, according to the Associated Press.
The Commercial Appeal previously reported Billy Turner had been arrested and charged with first-degree murder last Tuesday.
"The Lorenzen Wright case has stayed in the public eye for many years," Memphis Police director Michael Rallings said. "We said many times that we had never stopped investigating."
Along with Turner and Sherra Wright, "several others" could face charges as the investigation continues, per Mearl Purvis of WHBQ.
Memphis Police found a gun in a Walnut, Mississippi, lake last month.
"It's believed that this is the murder weapon," police spokesman Louis Brownlee told reporters.
Jon Wertheim of Sports Illustrated wrote about the cold case in October 2015, noting Lorenzen Wright made a 911 call on July 19, 2010, that featured at least nine gunshots. His body was recovered nine days later in a remote, wooded area in southeast Memphis.
Crenshaw reported the case's indictment file remained sealed.
