ST. PETERSBURG, Fla. (AP) - An early-morning shooting spree injured four people left St. Petersburg police with more questions than answers.
    
The incidents began around 2 a.m. Wednesday when police said they found a vacant, bullet-ridden vehicle with drugs inside. While they were investigating, a black limousine pulled up and passengers told investigators about another shooting scene about a block away.
    
Two of the 10 or so people in the limo had been shot, but police said their injuries weren't believed to be life-threatening.
    
Officers responding to the new location found a man inside a Chrysler 300 who had been shot.
    
A short time later police learned that another man had shown up at All Children's Hospital with gunshot wounds. That man drove himself to the hospital after being shot at the site of the Chrysler 300 shooting, said St. Petersburg police spokesman Mike Puetz.
    
All four victims have been hospitalized and police said one was in critical condition.
    
Investigators didn't know the motive early Wednesday and were still trying to sort out all the details from separate crime scenes.
    
Police are investigating a hit-and-run crash and a series of early-morning shootings in St. Petersburg.
    
Police spokesman Mike Puetz says it's not clear whether the incidents that began about 2:17 a.m. Wednesday are related.
    
At the first scene, officers found an unoccupied car that had been struck by bullets multiple times.
    
About 3:45 a.m., the officers were flagged down by occupants of a stretch limousine with two men suffering from gunshot wounds. The men were taken to the hospital in stable condition. Others inside the limo told police that someone in a black Chrysler 300 had shot at them.
    
As police investigated, they found a man in the Chrysler who had been injured in a shooting.
    
A short time later another man arrived at a hospital with bullet wounds.
