FORT LAUDERDALE, Fla., May 22 (UPI) -- Two men have been arrested in the slaying of a Fort Lauderdale body shop owner last week, and a third was still at large. Arrested were 21-year-old Keenan Clarke and 22-year-old Oliver Jones. They and a third man were seen arguing with Spurgeon Bowen before his shooting death May 12. Police say a part of a thumb was found at the scene and since Bowen and the other suspects had all 10 fingers, they speculate the digit belonged to the third man, who is still on the loose.
