Ryan Winicki , 40, was arrested for vehicular homicide in that case.

In both of those crashes the drivers are suspected of speeding and driving under the influence of alcohol.

Fatal crashes are becoming a disturbing trend across the Denver metro area, and police say those two factors are playing heavily into that trend.

“Speed is becoming more and more of a factor,” Denver police Lt. Rob Rock said. “We’re finding folks that are disregarding the speed limits 20 to 30 miles an hour over. People ask us all the time ‘Does speed kill?’ Yes it does.”

The first few months of this year have been particularly deadly.

So far this year there have been 21 fatal crashes in Denver compared to 16 at this time last year.
