LAWRENCEVILLE — A Tucker teen accused of killing his friend and setting ablaze the car that concealed her body is back in Gwinnett County, facing new charges after his extradition from Texas.
Boris Mejia, 18, is charged with murder in the slaying of Andrea Nassos, 18, of Stone Mountain. Mejia allegedly killed Nassos last month in her Tucker apartment, tried to bury the body at his home but resorted to setting Nassos’ Honda Accord on fire in Gwinnett’s Lucky Shoals Park.
A patrol officer found the smoldering car and firefighters discovered Nassos’ remains in the trunk.
Authorities said Mejia was driven by his father to Houston, where they have family. Houston police located Mejia and arrested him without incident a week after the body was found.
Gwinnett deputies booked Mejia in jail late Sunday night. He’s scheduled for a first appearance hearing — where his charges will be outlined but no evidence heard — this afternoon. The alleged killing happened in DeKalb County, where Mejia faces murder charges.
In Gwinnett, arson investigators have lodged new charges of criminal trespass and criminal damage to government property, in addition to arson.
The new charges allege Mejia was trespassing when he set fire to Nassos’ car, and that the burning vehicle damaged the government-owned park.
Authorities have not released a motive in the slaying. An autopsy showed Nassos, a recent Faith Academy graduate, suffered blunt-force trauma to the head. The autopsy also ruled out gunshot or stab wounds.
For his role, Mejia’s father, 51-year-old Ignacio Mejia, is charged in DeKalb with hindering the apprehension of a criminal and tampering with evidence, authorities said.
Police said the younger Mejia tried to bury Nassos at the Tucker home he shares with his father, who instructed his son to dispose of the body elsewhere before taking him to Texas.
