Harold Paul Rico (April 29, 1925 – January 16, 2004) was an FBI agent, indicted for murder in 2003.

In 1956 he recognized fugitive bank robber James "Whitey" Bulger in a Revere bar and arrested him.

Rico then watched as Portuguese-American hitman Joe Barboza committed perjury and claimed that he had committed Deegan's murder under orders from four made men in the Patriarca crime family: Peter Limone, underboss Henry Tameleo, Joe Salvati and Louis Greco.

When interrogated during U.S. House Judiciary Committee hearings in October 2003 about the four wrongful convictions, an enraged Rico responded, "What do you want, tears?

"[2] The two survivors and the estates of the deceased were awarded $101.7 million in damages by U.S. District Judge Nancy Gertner in Boston on July 26, 2007.
