Police are searching for the vandals who apparently torched more than a dozen campaign signs and American flags in a Howey-in-the-Hills veteran's yard.

William Overbay said someone ignited the flags and signs, which supported Republican presidential candidate Mitt Romney, that he had lined along his yard. The vandals also painted a sign on his driveway reading "Obama for life," at his DuPont Circle home, Overbay said.

"This is the first thing I saw was this sign painted on my driveway," Overbay said.

Howey-in-the-Hills police say no one left any clues behind to identify themselves. Overbay said as a Vietnam-era veteran, the hard feelings caused by the vandalism run deep.

"To give that many years for my country and to see it desecrated in such a despicable way angers me," Overbay said. "We have freedom of speech and to desecrate any kind of signs is absolutely despicable and a violation of the constitution of the United States."

UPDATE: The signs have been replaced by the Romney Tampa campaign office as of Friday afternoon. Click here to read more.
