One felony arrest was made for possession of a controlled substance in a correctional facility after a sobriety checkpoint conducted Friday night by the Boone Country Sheriff’s Department.

Three misdemeanor arrests were made at the checkpoint for driving while intoxicated. Two of the arrests were alcohol-related and the third was drug-related, according to a news release.

There were also two arrests made for driving with a suspended or revoked drivers license and four arrests made for driving with no valid drivers license.

The man arrested for a felony was originally arrested for driving with a suspended or revoked license and possession of less than 35 grams of marijuana during the sobriety checkpoint, according to the Boone County Sheriff’s Department website.

Deputy Robert Paul said the felony arrest occurred when the man took drugs into the jail, which is automatically a felony. Paul said people sometimes hide things in their clothing that is not checked on the street, but a more thorough check is conducted when they are brought into the jail.

“We get a handful of these every year,” Paul said.

The sobriety checkpoint took place in the 1300 block of Prathersville Road, according to the news release.

Paul said that when choosing a location, the sheriff’s department looks at the number of cars expected to go through and the manpower they have that night.

“We mix it up,” Detective Tom O’Sullivan said. “We do them at various locations throughout the county.”

O’Sullivan said the Sheriff’s Department conducts checkpoints about once every two months.

“We’ve been doing checkpoints around Halloween,” Paul said. “A lot of people have parties that weekend.”

According to the news release, 125 cars were checked at the checkpoint and five traffic stops were conducted. Paul said this number of cars was normal for the location, where they held a checkpoint last spring.

The checkpoint was conducted with the assistance of the Hallsville Police Department, according to the news release. O’Sullivan said sometimes other departments help them and sometimes they help other departments.

“It’s just another tool to take impaired drivers off the road,” O’Sullivan said.
