Authorities in San Marcos are searching for vandals who spray-painted a 300-year-old cypress tree on the San Marcos River.

The tree, the oldest and largest cypress on the section of the San Marcos River around Thompson’s Island Park, was tagged with images of a flower, heart, and the words "peace," "love" and "your soul is gold."

Authorities found the graffiti on July 1 in an area of the park that had been closed after flooding, and is expected to remain closed for the foreseeable future.

The graffiti had been removed by Tuesday, by city officials have not been able to track down any suspects in the case.

Though the park is closed, kayakers, canoers and tubers are still allowed to float through the area, but will not be allowed to stay on land any longer than necessary to get from one section of the river to another.

Anyone found in the park can be cited or arrested for criminal trespass, city officials said.

Anyone with information on the incident is asked to call Crime Stoppers at 1-800-324-8477 or the City Marshal’s Office at 512-393-8480. Crime Stoppers will pay up to $1,000 for information leading to the arrest of the person responsible.
