A Casper woman is now admitting to modified and more serious charges, after causing a number of wrecks on I-25.

Thirty-seven year old Amber Robles has pleaded guilty to one felony count of fourth DUI, and one misdemeanor count of reckless endangerment.

Troopers with the Wyoming Highway Patrol say in middle June, calls came in regarding a wrong way motorist, on I-25.

A short time later, another call came in that the vehicle had caused a crash near the Bryan Stock Trail exit.

When troopers arrived on scene they spotted Robles and said she was being uncooperative, plus there was an odor of alcohol coming from her.

Witnesses told investigators that Robles' vehicle was southbound in the northbound lane and then eventually was going northbound in the southbound lane and caused another crash, that resulted in four people going to the hospital.

Prosecutors say at the time, Robles' blood alcohol content was .24.

At the time of the wreck, she had 2 prior DUI convictions on her record and a third DUI in an unrelated case was pending.

Now she has 3 DUI convictions on her record, and since this is number four in less than 10 years, it is a felony.

As part of a plea deal, prosecutors will seek no more than a two and one-half to four year prison sentence.

Robles is being held on $20,000 bond, and will be sentenced at a later date.
