LAKEWOOD, Colo. (CBS4) – A semi driver has been arrested after a deadly crash involving at least 28 vehicles on I-70 near Denver Park West Thursday afternoon. Lakewood police identified the driver as 23-year-old Rogel Lazaro Aguilera-Mederos. He now faces multiple charges of vehicular homicide related to the accident.

At least four people are confirmed dead. Those four victims were each the single-occupant in their car.

“We’re still trying to identify what some of the cars even are,” said Ty Countryman with the Lakewood Police Department.


Aguilera-Mederos was hurt in the crash on Thursday afternoon, but not seriously. Ten people were rushed to Saint Anthony hospital. As of Friday morning, all of them had been released but one. He is in good condition, according to hospital officials.

The investigation has determined Aguilera-Mederos has a commercial drivers license from Texas. The truck Aguilera-Mederos was driving was hauling a load of 2×4 lumber.

“I can’t go into the facts, it’s still evidence we’re building. We feel at this time we have enough probable cause to charge vehicular homicide,” Agent Ty Countryman with Lakewood Police said.

Countryman did say at this time drugs and alcohol do not seem to be involved. A mechanical inspection will be done on the semi but the amount of heat from the damage may make that inspection incomplete.

Countryman did clarify, “We don’t have any indication that was an intentional act by the driver at all.”

Aguilera-Mederos will be advised of his rights and of why he is being held in court on Saturday, according to Pam Russell with the district attorney’s office. Bond may also be discussed during that hearing.  Charges will not be filed until his next hearing. A date for that hearing has not been set.

Investigators were still working to remove the wreckage of burned cars and semis on Friday morning.




The highway is not expected to reopen until Saturday.

    Illegal driver?

  3. Where does it say he is an illegal? He was licensed out of Texas. Can an illegal alien get licensed?

  4. David Patterson says:

    An illegal purposefully takes innocent AMERICAN lives and people still don’t think this is an invasion???

      David – you lie like a rug

      1. Ken Powers says:

        Heidi – Despicable you would would defend a murderous illegal.

  5. Check out HOW he even got a commercial Licence??

  6. Scott Ichiro says:

    Probably distracted driving, aka texting on his phone.

  7. Chris Snyder says:

    It looks like this wasn’t on a downhill grade, and even if so, he could have downshifted, turned off engine, or pulled off the road. He should have known about the traffic stoppage long before he got to it.

    Can’t find the article now, but maybe 10 years ago in San Jose a gravel truck driver ran into stopped cars while doing about 60 mph. I think he was the son or nephew of company and had a long record – he shouldn’t have been driving a truck. It was intentional and I think he was hopped up on meth. It says no drugs so far in this case, but just a couple days ago a nutcase ran down 8 people in Sunnyvale for ‘no reason’.. supposedly he was on his way to take food to a Bible Study.

      If you’re talking 20 years ago, his name is Grifall of Grifall trucking.

  8. Dan Kvasnicka says:

    that was done on purpose
