Police continue to search for a man who stole hundreds of thousands of dollars of collectible comic books from a northwest Wichita store.

Police say the man broke into the store on Nov. 19 and made several trips while he carried away about 40 items such as Avenger and Hulk comic books.

Mark Rowland, owner of River House Traders, says he lost more than $300,000 in the theft. But Rowland says he’s more upset because he’s owned some of the items for more than 50 years.

KAKE-TV reports there is no description of the suspect, only that he left in a dark-colored car.

Rowland now has a security system and says he will store some of his more valuable collectibles elsewhere.
