Memphis police have no official suspects in the murder of former NBA player Lorenzen Wright, and authorities said the case remains a "mystery" three months after his bullet-riddled body was found in a remote field.

"It is a mystery, but it's not cold," said police director Larry Godwin. "We have not placed it in the cold case file."

Wright would have turned 35 next week.

The father-of-six disappeared on July 19.
