A Swisher man was taken into custody Saturday night on suspicion of boating while intoxicated.

According to police, a DNR officer observed 40-year-old William Shanahan operating a vessel without a stern light after sunset, at approximately 8:15 pm. He was taken to shore and met by another officer, who conducted a sobriety test.

Shanahan reportedly had very slurred speech and slow deliberate movements. After showing indications of impairment on field testing, he blew a .148 percent blood-alcohol  content on a PBT and .147 percent on a Datamaster.

Shanahan was charged with OWI first offense, a serious misdemeanor.
