Two people with severe injuries were found Friday night in an Alexandria neighborhood just south of Four Mile Run, authorities said.
The two were both described as male. Police said they were found in a vehicle by officers who were summoned about 6 p.m. to the 500 block of Four Mile Road.
They were taken to a hospital with what police said were being described as life-threatening injuries.
No details were available Friday night on the nature of the injuries, or how they were inflicted. Nor could the ages of the victims be learned.
The street where they were found is a largely residential area of small apartment houses, just west of Mount Vernon Avenue.
The matter remained under investigation late Friday.
