POMPANO BEACH, Fla. (AP) - Nearly six years after a South Florida deputy was gunned down in a drugstore parking lot, authorities say they have compelling evidence about a possible suspect.
    
The Broward Sheriff's Office reports that Shawn Labeet may have been involved in the murder of Sgt. Christopher Reyka. Authorities said Tuesday they could not discuss most of the evidence, but did say Labeet was involved in drug rip-offs while he posed as an officer.  Authorities also said two witnesses placed Labeet in the area of the drugstore the night Reyka was murdered.
    
Labeet was killed in a shootout with police in 2007 after authorities said he shot four Miami-Dade police officers. Officer Jose Somohano was killed.
    
Police eventually tracked Labeet to an apartment complex, where he was fatally shot by the Miami-Dade SWAT team.
