A 13-year-old runaway from Irving was in jail Friday following his arrest in connection with the slaying of a man five days earlier at well-known drug house in south Dallas, police said.
The boy, whose name was not available because he is a juvenile, turned himself in to police on Tuesday, said Sgt. Gil Cerda, Dallas police spokesman.
He is accused of killing Byron Germaine Cobbs, 24, at a home in the 2700 block of Eagle Drive, Cerda said.
The neighborhood is southeast of the intersection of East Illinois Avenue and East Keist Avenue.
"According to witnesses, this is a known drug location," Cerda said of the house.
Investigators believe Cobbs went there at 11:30 p.m. Monday to buy drugs, and the suspect -- who had run away from his grandmother's home in Irving -- was there, Cerda said.
It was unclear on Friday if the boy was a drug dealer, Cerda said.
"We believe drugs were being sold from there, but we don't know exactly who all stays at that house," Cerda said. "We just know (the boy) was there that day."
The boy later told police that he believed the Cobbs was going to rob him and feared for his safety, Cerda said.
"So, he shoots him and takes off," Cerda said.
Officers responded and found Cobbs dead with a gunshot wound to the head, according to a police report.
The boy was being held Friday on a charge of murder at the Henry Wade Juvenile Justice Center in Dallas, Cerda said.
