Prosecutors say a Massapequa Park man knowingly downloaded videos of adults having sex with children as young 2 years old.

Dennis Grimaldi's neighbors on Linden Street were shocked when they heard about his arrest. One said Grimaldi "seems like a real nice guy."

Grimaldi pleaded not guilty to charges that include four counts of promoting a sexual performance by a child and two counts of possessing a sexual performance of a child. He's due back in court next Tuesday.

Grimaldi is known for singing in different bands across Long Island, including Soul Be It and Uppercut.
