WASHINGTON — Police are searching for people that might have seen an early Sunday morning Fairfax County Parkway crash that left two people dead and four others injured. The road was closed for several hours after the driver of a northbound 2004 Acura MDX lost control and crashed at about 2 a.m. in Reston, Virginia. Tonnisha McCoy, 21, of Sterling, and Joselyn Herndon, 23, of Reston, were pronounced dead at the scene, a Fairfax County Police Department release said. A total of four people were hurt in the crash but only two of them needed to go to the hospital. Preliminary findings determined that the driver lost control and the vehicle rolled over and left the roadway. Detectives believe speed and alcohol may have been factors. At least one other vehicle was on the scene during the crash and stayed when officers arrived, but police say the investigation is complex and they would like to speak with others that might have witnessed the crash or have information. Tips can be submitted anonymously through Crime Solvers or by calling 1-866-411-TIPS. They can also be sent via text by texting “TIP187” plus the message to CRIMES (274637). Anonymous tipsters are eligible for cash rewards of $100 to $1000 if their information leads to an arrest. A map of where the crash happened can be seen below.
