MARTINEZ -- The Contra Costa District Attorney's Office is asking for further investigation into a late-night stabbing in downtown Crockett on Saturday before it decides whether to file criminal charges against two brothers who were arrested in the attack.
Donald and Richard Zampa, the great-grandsons of famed ironworker Alfred Zampa, were expected to be released from County Jail on Wednesday evening since the DA's office has declined to immediately file charges, said deputy district attorney Brian Baker.
Donald Zampa, 21, was arrested on suspicion of attempted murder, and Richard Zampa, 24, was arrested on suspicion of assault with a deadly weapon around 2 a.m. Saturday after they allegedly stabbed a 29-year-old man during a fight near Second Avenue and Pomona Street.
The victim was flown to John Muir Medical Center in Walnut Creek, where he was treated for his wounds and has since been released.
Matthew Easterling, owner of Toot's Tavern, said his staff helped give first aid to the victim, who was lying in a "pool of blood."
"The dude was head to toe bleeding out," Easterling said. "If it wasn't for my buddies, he would have died."
Authorities are not commenting on whether the Zampa brothers knew the victim before the incident or what sparked the altercation.
The Zampas are like Crockett royalty, some locals say. Their great-grandfather, Alfred Zampa, who died in 2000, was celebrated for his contributions in the construction of various Bay Area bridges. The western span of the Carquinez Bridge is named after him, and he was one of the first workers to survive a fall from the Golden Gate Bridge during its construction.
"Everybody knows them," said Ken McBee, owner of Club Tac, a nearby saloon. "They are very respectable people."
The Contra Costa County Sheriff's Office is asking anyone with information about the stabbing to call 925-313-2600. Anonymous tips may be submitted by calling 866-846-3592 or by emailing email@example.com.
