(CBS/AP) MIAMI - 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 and now faces second-degree murder charges.
According to CBS Miami, Cabreja's body was found last weekend with a ligature tied tightly around her neck and a bag over her face.
An arrest affidavit says Granados and another man picked up Cabreja on Sept. 20, smoked crack cocaine at a park, and then went to an empty construction site. There, Granados says he attacked Cabreja and put her in a choke hold.
Police say that another man, who has not been identified, started hitting the victim.
The station reports an autopsy revealed Cabreja died from ligature strangulation and blunt force trauma.
Detective Rutland reportedly said, "It appears the motive was this man was under the influence of crack and that is when he lost control and killed her."
Authorities were questioning a man and a woman earlier this week, but have reportedly ruled them out as suspects after determining they were not involved in the crime.
The second suspect remains at large, according to the station.
