31 Austin St, Charlestown Near the shadows of 93 North, the 99 diner sits in a strip mall Charlestown.

What occurred at the 99 in Charlestown on Nov. 6, 1995 must have looked like a scene from a movie: As the crowd of lunchtime diners watched in horror, a father and son opened fire, killing four North End men in the restaurant in broad daylight, and wounding a fifth. Richard C. Sarro Jr., then 27, survived the attack. But his uncle Robert C. Luisi Sr., his cousin Luisi, his brother Antonio Sarro, and friend Anthony Pelosi Jr. were killed.

How did this unfold? Damien Clemente and Vincent Perez, who had been sitting in another booth, were allegedly threatened by the Luisi. Damien called his father from his cell phone. His father arrived, an argument turned into a bloodbath.

Anthony P. Clemente Sr. and his son, Damien, were later convicted of first-degree murder. Perez was aquitted on murder charges. The elder Clemente, who turns 54 on Sept. 14, is in custody at Souza-Baranowski Correctional Center in Shirley, while his son is doing time at the Old Colony Correctional Center in Bridgewater.
