Authorities have not made an arrest in a road rage shooting that happened on Memorial Day, even though the victim said he followed the suspect long enough to provide a description of the vehicle and the shooter.

San Antonio police classified the case as aggravated assault involving the discharge of a firearm from a motor vehicle at another vehicle, causing serious bodily injury, according to a police report.

The victim, who asked not to be identified and is being referred to as "Jake," said the shooting happened as he was merging onto northbound Interstate 35 near Division Avenue.
