MIAMI (AP) - Police have arrested a suspect in the death of a South Florida teenager whose body was found dumped at a construction site after witnesses reported seeing a body fall from a truck.
    
Investigators said Friday they've arrested 20-year-old Fernando Granados after receiving a tip. They say he confessed to strangling 18-year-old Tiffany Cabreja. He faces second-degree murder charges.
    
An arrest affidavit says Granados and another man picked up Cabreja from on Sept. 20, smoked crack cocaine at a park, then went to an empty construction site. There, Granados says he attacked Cabreja and put her in a choke hold.
    
Police say that the other man started hitting her. They haven't identified him.
    
She was found with a ligature around the neck and a bag over her face.
