Hennepin County Sheriff David Hutchinson is suspected of driving while under the influence of alcohol when he crashed a vehicle early Wednesday in western Minnesota, state authorities said.

The rollover wreck occurred about 2:30 a.m. on eastbound Interstate 94 about 5 miles east of Alexandria, where Hutchinson was attending the Minnesota Sheriffs' Association conference.

Hutchinson suffered noncritical injuries and was taken by ambulance to Alomere Hospital in Alexandria, the State Patrol said.

No one else was in the unmarked Ford Explorer, which is owned by Hennepin County.

The 41-year-old Hutchinson acknowledged in a statement to making the "inexcusable decision to drive after drinking alcohol."

Douglas County sheriff's deputies responded to the crash scene "and suspected impairment," according to a statement from the State Patrol that made no reference of Hutchinson's elected post.

A state trooper obtained a warrant and collected a urine sample from Hutchinson "to determine impairment, which is standard procedure when impairment is suspected in a crash and a person is transported to the hospital," the statement continued.

Charges are pending based on the results of the sample and a review by the Douglas County Attorney's Office.

Hennepin County Sheriff's Office spokesman Andy Skoogman said that Hutchinson, who is elected by voters, is not subject to any disciplinary action by the county in the same manner as a deputy might be for certain actions.

Skoogman said the office will be run by Hutchinson's command staff and chief deputy.

Hutchinson, who lives in Bloomington, released his own statement acknowledging that he is being investigated for driving under the influence and suffered "serious but non life-threatening" injuries.

"I made the inexcusable decision to drive after drinking alcohol, and I am deeply sorry. As the chief law enforcement officer in Hennepin County, I am held to a higher standard. I regret the choice I made and apologize to the citizens I serve, the staff I work with, and the friends and family who support me.

"I take full responsibility for my actions and am prepared to accept the consequences of my poor decision. I am relieved that no one else was injured in the crash. I will immediately address my personal issues surrounding alcohol and seek the help I need to continue to serve the people of Hennepin County."

It was not immediately clear where Hutchinson was drinking or who he was with in the hours leading up to the crash.

The Sheriff's Office was alerted by the state Department of Public Safety that it would be sending out a news release about the crash, said agency spokesman Bruce Gordon. Hutchinson's 140-word statement was released moments later.

Court records in Minnesota show only one traffic conviction for Hutchinson: a misdemeanor in Hennepin County in 2013 for failure to display vehicle plates.

Hennepin County Board Chair Marion Greene said in a statement, "I am relieved that no one else was injured in the crash involving Sheriff Hutchinson, and that as far as I know the Sheriff is doing fine. It appears Sheriff Hutchinson is taking responsibility for his serious actions both professionally and personally, and I wish him the best on his steps towards recovery."

Commissioner Debbie Goettel said she is glad to hear that he is seeking help "and will accept responsibility for his choices. I don't expect to see any disruptions to public safety operations."

Assistant County Administrator for Public Safety Mark Thompson, whose office oversees the sheriff, said, "It is unfortunate to hear the sheriff was involved in a crash. Apparently, he suffered some injuries, but no on else was injured. Being a leader in law enforcement is difficult these days."
