Significant Matters

Below are matters chosen by the firm to highlight.

The Isaacs Law Firm and its attorneys practice primarily in criminal defense litigation and personal injury cases in state and federal courts throughout Tennessee. Mr. Isaacs has successfully handled a number of high profile cases that have gained national attention, a few notable cases are set out below:

  • State v. Norman Clark: a high profile double homicide case wherein the Isaacs Law Firm obtained a favorable result for Mr. Clark. This case was recently featured on Dateline NBC. Clark was facing two counts of First Degree Murder and two counts of felony murder related to the death of an ex-girlfriend and her unborn child. Following a hotly contested trial, the jury was ultimately deadlocked and unable to reach a verdict unanimously resulting in a mistrial. Following a second mistrial by successor counsel in 2017, the State decided to reexamine their options. In 2018, the Knox County Attorney General’s Office decided to nolle prosequi the case against Mr. Clark ending the prosecution.
  • State v. Thomas “Zoo Man” Huskey: In this landmark case, Mr. Isaacs represented one of the most infamous alleged serial killers in recent Tennessee history. Thomas “The Zoo Man” Huskey stood trial for four capital homicides in addition to four counts of rape. The extensive litigation in this case gained significant national and international attention based on salient facts including Mr. Huskey’s multiple personalities and the fact that he was Knox County’s only reputed serial killer. After more than a decade of extensive litigation, Mr. Isaacs and the defense team were able to obtain two hung juries, and the murder charges against Mr. Huskey were ultimately dismissed.
  • United States v. Foust, a case portrayed in the novel Dark and Bloody Ground wherein Mr. Isaacs obtained a not guilty verdict for his client who was accused of laundering money obtained through of brutal murder of a Kentucky physician and his teenage daughter.
  • State v. Michael Frazier: Mr. Frazier’s case was one of the first Tennessee cases to be televised by Court TV. Mr. Frazier, a prominent newspaper editor, was accused of attempting to murder the husband of a woman he profiled in a story and allegedly had an affair with. Mr. Isaacs successfully litigated the case, landing an impressive verdict of attempted manslaughter.
  • State v. Kenneth “Kenny” Bartley: Kenny Bartley was a Campbell County youth who stood trial following a school shooting that resulted in the death of the school principal and injuries to two others. Bartley initially pled guilty to second degree murder under the advice of his original attorney. On Post-Conviction review, Mr. Isaacs was successful in convincing the court that Mr. Bartley’s initial counsel was ineffective, and ultimately securing a new trial for Mr. Bartley. The next step was a jury trial wherein Mr. Isaacs obtained a jury verdict of reckless homicide, resulting in Mr. Bartley’s immediate release after serving eight years in custody.
  • The Isaacs Law Firm has also represented a number of prominent individuals within the Tennessee and Knoxville communities including local sheriffs and State Representatives. This representation has spanned various state and federal courts.
  • The Isaacs Law Firm has achieved numerous victories in both appellate and post-conviction cases. In State v. Phillip Pack, The Isaacs Law Firm successfully obtained release of Mr. Pack who had been convicted by a jury of murder. In a scathing appellate opinion, the Tennessee Court of Criminal Appeals reversed the conviction against Mr. Pack, noting the case was one in which there was “not a scintilla of evidence”.
  • In State v. Harland Pollard, the Isaacs Law Firm successfully litigated a federal habeas corpus petition challenging his plea to second degree murder for stabbing his wife fourteen times. This sentence was vacated by the federal court.
  • In United States v. Joseph Armstrong, our legal team was able to secure an outstanding result for one of the most recognized legislators in Tennessee. Mr. Armstrong, a veteran member of the Tennessee General Assembly who had served over 28 years in office, was facing three separate federal charges including conspiracy to defraud the United States, attempt to evade taxes, and filing a fraudulent tax return. Following a four-day jury trial, Mr. Armstrong was acquitted of the conspiracy and tax evasion charges. After a contentious sentencing hearing against the United States, our team convinced the Court to place Mr. Armstrong on probation with a period of house arrest rather than imposing a sentence in the federal penitentiary as requested by the Government.
