MANSFIELD -- They started June 13, a string of suspicious fires throughout Mansfield that have now totaled 28.
Fire Chief John Harsch says 22 of the fires were started in vacant buildings, mostly abandoned homes.
Penny and Paul Harriger are surrounded by several vacant homes in their neighborhood. On Thursday, one behind their house was set on fire.
"I'm scared for my family," Penny says.
Harsch says some of the fires may not be connected, but it seems clear someone is setting others intentionally.
"There's three reasons for arson -- revenge, profit or gratification, I don't think the first two reasons apply to abandoned homes," Harsch says.
There is a $5,000 reward being offered by the Blue Ribbon Arson Committee for information that leads to the arrest and conviction of those responsible.
