Brother, sister found shot to death on Gwinnett County interstate, police say

BUFORD, Ga. (Atlanta News First) - The shooting deaths of a brother and sister in Gwinnett County are under investigation and police are asking for information on what led up to their deaths, according to the Gwinnett County Police Department.

On Aug. 27, the brother and sister, later identified as Juan Angel Montes, 16, and Maria Rosaria Montes Dorantes, 23, were found dead on the shoulder of the I-85 and 985 split, police said. They were found shortly before 7:30 p.m. in the grass by someone passing by.

The person who found the two told police they pulled over because of car troubles, according to an incident report. They told police the brother and sister were bleeding, not conscious and not breathing, the incident report states.

Police said there were no vehicles near them when they were found.

“Detectives are trying to figure out what events lead up to the homicide,” said Gwinnett County Police Sgt. Michele Pihera. “Right now, we don’t know if this is going to be a road rage event simply because the victims didn’t have a vehicle there on the side of the road where their bodies were found. So this likely will probably not be the case, but we’re urging anybody with information to come forward to call us or call Crime Stoppers.”

Police said the medical examiner’s office found the two died from gunshot wounds.

A family member told Telemundo Atlanta that the two went to a concert and then were going to meet their sisters.

Gwinnett County Police said the bodies were likely there not more than a day or two before the victims were discovered.

Anyone with information is asked to call Gwinnett County Police Department at (770) 513-5300 or Crime Stoppers at (404) 577-8477. You can also report anonymously online.
