Sioux Falls police say they've identified six teenagers responsible for vandalizing a well-known downtown bookstore more than a week ago.

Unlike initial thoughts by the co-owner that two eggings on the weekend of Feb. 15 was targeted at Full Circle Book Co-op's transgender flag, police think the incident was not tied to any sort of hate crime, police spokesman Sam Clemens said.

"There wasn't anything substantial to anything to do with a hate crime," Clemens said. "Sounds like basically, they knew who the owner of the store was and didn't like him."

The business had started displaying the pink-and-blue flag the week prior to the incident in light of three transgender related bills before the South Dakota legislature at the time that drew national criticism.

One of the bills was recently killed, and another has been withdrawn by its sponsor.

"It appeared to be targeted at our transgender flag, co-owner Jason Kurtz said at the time. "We think it was a reaction to that."

The incident is tied to other eggings at cars downtown in parking garages, Clemens said.

Five of the teenagers are considered to be juveniles, or under the age of 18, while the sixth could face consequences as an adult if state's attorneys decide to press charges.

The Sioux Falls Police Department has sent information about the case to the Minnehaha and Lincoln County state's attorney's offices for review.
