A St. Paul man, Jon Ross Wentz, was sent to prison Thursday for causing a head-on collision that severely injured a two-time Stillwater state hockey champion and her sister in August 2012.

Wentz, now 47, pleaded guilty on Dec. 19 to two counts of criminal vehicular operation while drunk. He was driving westbound on Hwy. 5 in Lake Elmo when his car veered over the centerline, crashing into Marah Sobczak, 20, and her sister Kalley, 15.

His vehicle had been reported earlier as being "all over the road," according to the complaint filed in Washington County District Court. A test at Regions Hospital after the crash showed his blood alcohol content at 0.08 percent.

Marah Sobczak, a hockey champion at Stillwater Area High School, was about to start her junior year as a goalie on the Gustavus Adolphus College hockey team at the time of the crash. She and her sister underwent extensive medical treatment for leg, spine and traumatic brain injuries.

District Judge John McBride sentenced Wentz to 33 months in St. Cloud prison on one felony count, with credit for 238 days already spent in jail. On the second count, McBride sentenced Wentz to five years of supervised probation that will begin after he completes his prison sentence.

He also was ordered to pay restitution from prison wages.

Wentz has been charged numerous times with theft, domestic abuse and traffic offenses. He had a drunken driving conviction in August 2011, Washington County Attorney Pete Orput said.
