Evidence collected from two blazes about a mile apart in the Pinelands gives "clear indication" the fires were set, a state fire official said Sunday.
The blazes in the Winslow Wildlife Management Area in Camden County, on the south side of the Atlantic City Expressway, scorched about 400 acres Friday. The fires were still smoldering Sunday but had been contained, authorities said.
No specific cause of the fires had been determined, nor had any suspects been identified.
The fires were set between Thursday evening and Friday morning, said Michael Drake, acting state fire warden for the state Forest Fire Service. He declined to give details about the evidence, which was collected during the blazes and on Saturday.
