Boy, 17, woke up at bottom of 40 foot deep river trapped INSIDE friend's car that crashed through railings - here's how he escaped

A 17-year-old has shared his harrowing tale of survival after he woke up trapped in a car submerged dozens of feet under a Portland, Oregon river. 

DJ Buckner and three others were passengers in 19-year-old Roberto Garcia-Chavez's white 1996 Toyota Corolla when Garcia-Chavez saw a police car and 'took off' around 2am on Monday, according to Traffic Investigations Unit Officers.

DJ was in the back seat when Garcia-Chavez tore through a park before crashing through fencing above the 40-foot-deep Willamette River, plunging the vehicle into the murky waters below.

The 17-year-old was the only survivor. On Thursday, the Portland Medical Examiner identified Garcia-Chavez and Trent Badillo, 17, as two of the victims. The identity of the third victim, believed to be a 20-year-old man, has not yet been made public. 

DJ's mother, Melissa Buckner, told The Oregonian that her son believes he hit his head in the crash and was knocked unconscious. 

He was suddenly jolted awake when he began inhaling water. 

'He just remembers he needed to grab his seatbelt and find the buckle,' Melissa told the Oregonian. 'He said he was swimming forever.'

Brian Hughes, Assistant Chief of the Portland police, said that the officer the group fled from did not pursue their vehicle. The officer only discovered what had happened after he pulled up next to the park and saw part of the fence missing.

The policeman then saw DJ treading water. The 17-year-old's mother said that as soon as her son reached the surface, he began shouting that his three friends were still in the water. 

Hughes said the officer who spotted DJ quickly called the US Coast Guard and Portland Fire and Rescue. 

The 17-year-old was transported to a hospital for treatment while first responders unsuccessfully attempted to rescue the others.

Later on Monday, Multnomah County Sheriff’s Office divers searched the bottom of the river and recovered the bodies of Garcia-Chavez and Badillo. The search for DJ's third friend, who is presumed to be dead, is ongoing.

Melissa recounted the terrifying phone call she received at 3:30am informing her that her son was in the hospital. 

'I didn’t know that they had crashed,' she told the Oregonian. 'I didn’t know anything other than my son was in the hospital and I needed to get there.'

When she arrived, she found her son had suffered a fractured nose, black eyes and bruising. 

'Physically, he’s hurting. He’s not feeling good,' she said. 'Emotionally, it’s starting to hit him, but I’m sure he’s got a lot more to work through.'

Melissa said that her son and his friends had been on their way home when Garcia-Chavez saw a police car and 'took off.' 

Portland police said the white Corolla began speeding in the opposite direction of traffic and running red lights. 

When an officer turned on his police lights to get the vehicle to stop, Garcia-Chavez fled down other streets before driving through Tom McCall Waterfront Park and crashing into the river. 

During the chase, DJ was shouting, 'Slow down, slow down, you’re going too fast!' according to his mother. 

Garcia-Chavez's sister, Yanett Garcia-Chavez, told KOIN she does not know why her brother chose to flee from police.  

She told the outlet he was a good kid who was active in JROTC and had planned to join the military before deciding to stay closer to home.

'There’s nothing that we can do now. We can’t go back in time. I can’t do anything to bring my brother back,' Yanett told KOIN. 

Yanett added that she does not blame anyone and is simply heartbroken by the situation.

DJ's mother echoed that sentiment. She told the Oregonian: 'Every one of them, they’re very, very good boys, just made a stupid mistake.'
