LEE COUNTY, Fla. - Vandals, again, have attacked one of the greens at San Carlos Golf Course - pouring pesticide all around the hole.

Crews believe sometime between June 30 and July 2 someone damaged the turf on the 4th green.

An employee told deputies an unknown substance, possibly herbicide or pesticide, was sprayed or poured on the grass, causing it to die.

The same course was vandalized by a homeowner in 2010. Neighbors say the course has been a target for the past several years.

Depties have not identified a suspect in the latest case.
