Forty-two-year-old Robert Leroy Johnson faces life in prison in the October 2010 death of Thomas Francis Datema. District Attorney spokeswoman Casimir Spencer the jury deliberated two hours before returning a guilty verdict Wednesday.
Johnson told police that he shot Datema after the man harassed him for sex. Prosecutors say Johnson told police that he lured the man to a remote county road and shot him in the head.
Johnson then caused a bomb scare when he arrived at the jail to turn himself in with Datema's body in the trunk.
Sentencing is scheduled for Jan. 3.
