AP: Colorado bomb suspect wearing Gamecock baseball cap

The new photos of the man show him riding a public bus away from Southwest Plaza Mall on Tuesday evening, the night before the fire.

They provide the best view yet of the man, who has a grey mustache. He has on the same clothes he wore in previously released photos of him at the mall Wednesday.

The latest photos show a University of South Carolina logo on his baseball hat.

Authorities originally considered the man a person of interest in the case, but Jefferson County sheriff's spokesman Mark Techmeyer said Friday that information from the investigation led investigators to consider him a suspect. Techmeyer wouldn't elaborate.
