Gwinnett county police charge three teenagers in last week’s murder of a young man near Suwanee.

The three, identified as 17-year-old Franecha Torres, 17-year-old Nicholas Evans and 18-year-old Khalil Miller, were already in jail for a couple of armed robberies in the city of Suwanee.

Sgt. Jake smith says those crimes led to them as suspects in the murder of 21-year-old Willian Tunchez of Lawrenceville.

“We received a tip regarding the identity of one of the suspects. The investigation into that suspect led to the identity of the other two, and all three were identified as being at the scene at the time of our homicide case,” he tells WSB’s Sandra Parrish.

The body of 21-year-old Willian Tunchez was found by children on a neighborhood trail on Northcliff Drive near Suwanee. His truck was parked along the curb a few houses down from where his body was discovered shot to death. Arrest records show one of the three suspects lives in that neighborhood.

Tunchez was reported missing by his father the night before his body was located.

Smith says robbery appears to be the motive and is similar to the armed robberies that occurred in Suwanee.

“We don’t think the suspects and the victim knew each other. But we do believe it was set-up robbery. So, one of the suspects did have some… sort of conversation with the victim prior to the crime occurring,” he says.

The three suspects are charged with felony murder and armed robbery in addition to the armed robbery charges they face in Suwanee.
