BILLINGS, Mont. -

Yellowstone County authorities have not made an arrest in the shooting death of a Billings man more than two weeks after his death.
    
Sheriff Mike Linder is tight-lipped about the case, saying he can't give out any information that could potentially jeopardize it.
    
Linder told the Billings Gazette Wednesday that evidence has been sent to the crime lab and detectives are investigating, but he won't say whether any suspects have been identified.
    
Frank Richey Greene was found outside his workshop on March 8. His girlfriend discovered the 47-year-old Greene's body that night when she went to check on him.
    
He had been shot several times.
    
A neighbor reported seeing a pickup truck leaving the area. The driver was questioned and released.
