Gwinnett Police arrest a teenager in connection with the death of an honors student found in her burning car.

Andrea Nassos, 18, was last heard from the evening of Thursday, May 19, when her father Pete said she was headed to work.   But the teen never showed up there.  The next morning, a body was pulled from a smoldering car at Lucky Shoals Park in Tucker.

WSB's Pete Combs reports police have now charged 18-year-old Boris Mejia in the case.

"He is part of Andrea Nassos' circle of friends," says Gwinnett Police Corporal Jake Smith.

Mejia was arrested by police in Houston, Texas.  He first surfaced as a suspect May 25.

Cpl. Smith tells WSB that is when detectives went to the teenager's house in Tucker, and found that he wasn't there.  Interviews with relatives, including his 50-year-old father Ignacio Mejia, revealed that Mejia had killed Andrea at her DeKalb County apartment, then tried to bury her body in his father's back yard in Tucker.

"Ignacio kind of discovered what was going on, and Boris at that point took Nassos' body and her vehicle to Lucky Shoals Park where he set it on fire," says Smith.  "Following the arson, Ignacio drove Boris to Houston, Texas, and left him there."

The teen was arrested there earlier this week.  Mejia is being brought back to metro Atlanta, where he will face charges in both Gwinnett and DeKalb Counties.  Charges will include murder, arson, and tampering with evidence.  The elder Mejia will be charged with tampering with evidence and hindering the apprehension of a criminal.

"We're not really speculating on motive at this point," says Smith, who adds that the damage from the fire made it difficult to determine her precise cause of death--but that it was clear Nassos was the victim of a homicide.
