Retail theft arrests declined from 90 in 2015 to 61 in 2016, with the majority of incidents taking place at Walmart.

In Columbia, officers handled 276 crashes in 2016. That is just one more crash than in 2015. Eight of the crashes were alcohol-related in both 2016 and 2015.

Columbia Police Chief Jerry Paul expressed concern with the increase in violence against police officers in his town. There were 11 arrests for resisting arrest or obstructing justice in 2016 compared to just four such incidents in 2015.

“It’s definitely a concern,” Paul said. “We’ve seen more incidents of damage to police cars and cases where the individuals are being more aggressive with the officers.”

Retail theft reports increased in Columbia as well, from eight (eight arrests) in 2015 to 14 (nine arrests) in 2016.

The number of sex offenses increased in Columbia, from just five reports with one arrest in 2015 to four reports with nine arrests in 2016.
