ST. LOUIS -- St. Louis firefighters said Sunday they have responded to 10 suspicious fires in recent days, and investigating whether an arsonist is at work in the city, according to KSDK-TV.

Officials said all the fires were set outside of vacant buildings within five blocks of north St. Louis. Five of the suspect fires blazed Saturday night.
