WHEATON, Ill. — A suburban Chicago businessman is charged with murder in the shooting death of a former European-league basketball player.

A DuPage County judge on Friday denied bail for 51-year-old Jeffrey Keller, the CEO of an Internet company. He’s accused of stalking and killing 37-year-old Nate J. Fox of Bloomingdale in December.

Prosecutors say that Keller believed Fox was having an affair with the same woman with whom Keller was “emotionally” involved.

Fox was shot to death on his way home from work and later died at a hospital.

Fox’s obituary said he graduated from Plainfield High School and got a basketball scholarship to Boston College. He later transferred to the University of Maine and, after graduation, played professionally throughout Europe from 2000 to 2012.

Keller’s next court date is Jan. 21.
