Bartow, Florida -- As the murder trial for Alejandro Baez-Garcia is about to get underway, the court is trying to figure out what to make of a letter - written by someone claiming to be the "real" killer.
Is it real or a ploy?
The case involves 19-year-old Alejandro Baez-Garcia who is accused of killing a Lakeland teenager.
Baez-Garcia was arrested in January 2011, just hours after the shooting that killed 19-year-old Juan Castillo and critically injured his 11-year-old brother Jake Castillo.

At the time, Polk County Sheriff Grady Judd said the pair had been targeted because Juan Castillo was wearing rival gang colors.
Deputies arrested Baez-Garcia, who they say later confessed to the shooting, telling officials the shooting happened as a van drove past the victims' house. Detectives said there were five people were inside the van.
