Crash investigation 

What we know:

D.C. Fire and Emergency Medical Services said they received a call about the incident just before 7:00 p.m., stating a vehicle became submerged in the river following the crash. 

After divers were dispatched to assess the situation and recover the vehicle, officials said one person was brought to shore and is receiving advanced life support. 

One person from the other vehicle that was involved in the collision on the bridge was transported to the hospital with minor injuries.

D.C. Fire and EMS said that no other victims were found during secondary searches around the sunken vehicle.

What we don't know:

The exact circumstances of the crash remain unclear. However, Fox 5 did speak to an eyewitness to the crash who said the pick-up truck hit another car before veering across incoming traffic and crashing into the river. 

Nigisti Adane took dashcam video showing what led up to the crash. She estimated the driver was under the water for at least 15 minutes before first responders arrived on scene. 

"I called at 6:48, and when the cops came it had been 15 minutes at that point," Adane said. "The truck went straight down. I think usually, I assumed that cars would float a little bit, but it looked like it went straight down." 

Authorities have not identified the drivers or passengers in the vehicles involved.
