ROCKVILLE, Md. (WUSA) - A woman complained of pain and died after her car struck the vehicle in front of her on Rockville Pike on Wednesday, according to  Montgomery County Police.

The collision happened at approximately 7:35 a.m. Officers responded to the intersection of Rockville Pike and Old Georgetown Road. When police arrived, both drivers were outside of their vehicles and walking around in the area.

The driver of a gold 2005 Ford Taurus had been slowing for traffic when it was hit from behind by a green 2000 Chrysler Sebring. While officers were speaking with the drivers, the Chrysler Sebring driver complained of pain. An ambulance was requested to take her to a hospital. In the ambulance, she lost consciousness, and was pronounced dead at the hospital.

OLNEY, Md, (WUSA) -- They walked in silence through the tall grass of a park in Olney to reach a spot that conjures the saddest of memories.

It was exactly one year ago that 20-year-old Kevin Coffay was driving drunk on a winding section of Route 108, lost control of his car and slammed into the woods, killing three of his passengers: 18 year-old Haeley McGuire, 18 year-old Spenser Datt, and 20 year-old Johnny Hoover.

On Tuesday, with heavy hearts under their matching bright green shirts, friends and family members held a candlelight vigil, and laid a wreath at the tree where their loved ones' lives came to an end.

Kevin Coffay initially received 20 years in prison, but a judge recently reduced the sentence to eight, and it's possible he could be a free man again sometime next year.
