Deactivating Testimonial Author Link

Greetings, I am using testimonials (free Catch Responsive) on my homepage to highlight a few quotes. I like that the author (source) is included below the testimonial but I'd prefer that the author not be a live link. Is there a CSS code that can deactivate these three links on my homepage?
