Mr. Buckley believes that every person is worth defending and that none of us should be defined by our worst day – no matter what the allegations may be.

Prior to opening this firm in 2013, Mr. Buckley trained for over a decade under some of the nation’s top criminal defense lawyers.

NOTABLE CASES

 

Every case is different, and past results do not predict future outcomes in other cases.

In 2021, Mr. Buckley secured the dismissal of all criminal charges against his client, [Name Expunged], an attorney accused of attempting to strangle his child’s mother (who was a judge). By the time of trial, the alleged victim refused to testify in court and Mr. Buckley successfully suppressed her prior recorded statement to police – leaving prosecutors with no evidence.

In 2019, following a 75-day federal jury trial, Mr. Buckley and co-counsel Jim Lavine won a stunning “Not Guilty” jury verdict for their client, Jeffry Cockerell, who was indicted for allegedly participating in a $120 million federal healthcare fraud conspiracy. Following the “Not Guilty” verdict, Mr. Buckley secured an order forcing the federal government to return $3 million they seized from Mr. Cockerell at the time of his arrest.

In 2018, Mr. Buckley secured the dismissal of all federal charges against his client, Dr. Ed Jacinthe, a physician charged with Healthcare Fraud and Conspiracy. Mr. Buckley successfully demonstrated to prosecutors before trial that Dr. Jacinthe did not commit fraud when he signed orders for services reimbursed by Medicaid, even though the services were later found to be medically unnecessary. 

In 2016, Mr. Buckley served as co-counsel and diplomatic liaison for his client, Larry Davis, a U.S. citizen charged with drug trafficking in the Dominican Republic after U.S. DEA agents and Dominican officials boarded Davis’s boat and found 980 kilos of cocaine stashed inside. After a lengthy trial in the capitol city of Santo Domingo, a panel of Dominican federal judges found Mr. Davis “Not Guilty” and ordered his release. 

In 2015, Mr. Buckley won the pretrial dismissal of federal tax evasion charges for his client, Richard Armaugh. A federal district judge agreed with Mr. Buckley’s argument that Mr. Armaugh’s speedy trial rights were violated when federal agents took 9 years to find him in Ecuador, extradite him to the U.S., and bring him to court to stand trial.

In 2014, Mr. Buckley won a “Not Guilty” jury verdict for his client, [Name Expunged], who was charged with drug possession after police found baggies of cocaine in her pockets. In a “Hail Mary” pass with no other options, Mr. Buckley successfully pulled off the mythical “borrowed pants defense” by arguing that his client borrowed her shorts from another woman and then wore them without checking the pockets. The jury acquitted based on reasonable doubt. 

In 2011, Mr. Buckley won a “Not Guilty” jury verdict for his client, Jason Palmer, a law enforcement officer charged with Murder in the shooting of a known gang member. While prosecutors alleged that Mr. Palmer killed the alleged victim “execution style” in retaliation for past threats, Mr. Buckley successfully convinced the jury that Mr. Palmer acted in self-defense.

In 2004, Mr. Buckley successfully exonerated his client, John Michael Harvey, who was serving a 40-year prison sentence for a child sex crime he didn’t commit. Mr. Buckley used the alleged victim’s recantation to prove Mr. Harvey’s innocence, overturn his conviction, and win his release.
