WARREN -- Part of a roadside memorial caught fire at the site where sixteens died last week.
The fire chief in Warren says it's not clear whether the fire was deliberately set or perhaps ignited by burning candles at the memorial.
Firefighters say part of the display already was destroyed when they got to the fire early Monday.
Funeral services were held Monday for three of the six teens who died.
The teens drowned when a sport utility vehicle there were riding in struck a guardrail and flipped into a pond in Warren.
