Question: What forensic psychiatrist consulted on numbers cases including one for a contract killer associated with the DeCavalcante crime family?
Context: Richard Leonard Kuklinski (April 11, 1935 – March 5, 2006) was an American contract killer and serial killer who was convicted of murdering five people, though he likely killed at least several dozen more.  He was associated with members of the American Mafia, namely the DeCavalcante crime family of Newark, New Jersey, and the Five Families of New York City. The DeCavalcante crime family is an Italian-American organized crime family that operates in Elizabeth, New Jersey and surrounding areas in the state and is part of the nationwide criminal phenomenon known as the American Mafia (or Cosa Nostra).  It operates on the other side of the Hudson River from the Five Families of New York, but it maintains strong relations with many of them, as well as with the Philadelphia crime family and the Patriarca crime family of New England.  Its illicit activities include bookmaking, building, cement, and construction violations, bootlegging, corruption, drug trafficking, extortion, fencing, fraud, hijacking, illegal gambling, loan-sharking, money laundering, murder, pier thefts, pornography, prostitution, racketeering, and waste management violations.  The DeCavalcantes are, in part, the inspiration for the fictional DiMeo crime family of HBO's dramatic series "The Sopranos".  The DeCavalcante family was the subject of the CNBC program "Mob Money", which aired on June 23, 2010 and "The Real Sopranos" TV documentary (first airdate April 26, 2006) directed by Thomas Viner for the UK production company Class Films. Simone Rizzo "Sam" DeCavalcante (March 3, 1912 – February 7, 1997), known as "Sam the Plumber", was a member of the New Jersey Mafia.  Claiming descent from the Italian royal family, DeCavalcante was nicknamed "The Count".  The Kefauver hearings later named his crime family the DeCavalcante crime family since he was the boss of the family current to those hearings. Joseph "Joe" Miranda (born 1925) is an American mobster and member of the New Jersey-based DeCavalcante crime family.  A longtime "soldier" to Simone "Sam the Plumber" DeCavalcante and later boss Giovanni Riggi, he became acting underboss for Girolamo "Jimmy" Palermo following the imprisonment of many high-ranking members in 2003. John "Johnny Boy" D'Amato (died January 1992) was a New Jersey mobster and former acting boss of the DeCavalcante crime family.  After being recruited by Gambino crime family boss John Gotti to take over the family, he was suspected of engaging in homosexual activity and was murdered in January 1992. Philip Abramo (born 1945), also known as "The King Of Wall Street", "Lou Metzer" is a caporegime in the New Jersey DeCavalcante crime family who was allegedly involved in security fraud and murder.  Abramo was a capo of the DeCavalcante family's crew in Miami, Florida. Park Dietz (born 1948) is a forensic psychiatrist who has consulted or testified in many of the highest profile US criminal cases including Joel Rifkin, Arthur Shawcross, Jeffrey Dahmer, The Unabomber, Richard Kuklinski, the Beltway sniper attacks, and Jared Lee Loughner.

Welner is also known for a number of innovations in forensic science, forensic psychiatry and justice, including protocols for prospective peer review in forensic medicine consultation, research to standardize an evidence-based distinction of the worst crimes, The Depravity Standard, and recommendations for upgrading forensic science assessment.  He has been featured in network television news coverage of forensic psychiatry issues, has authored publications for professional and public audiences, and has contributed to emerging legislation on mental health reform. Francesco "Fat Frank" Majuri (April 18, 1909 – 1983) was a New Jersey mobster and the former consigliere of the DeCavalcante crime family.  His son is Charles "Big Ears" Majuri, a longtime recognized Captain in the Newark faction of the same crime family. Giacomo Michael "Jackie" Aprile Sr., played by Michael Rispoli, is a fictional character on the HBO original series "The Sopranos".  He was the first acting boss of the DiMeo Crime Family, after longtime reputed boss Ercole 'Eckley' DiMeo was sent to prison in 1995.
