Criminal Defense and Post Conviction

Criminal Defense Investigators in Los Angeles, California

Criminal Defense Investigators for Attorneys, Defendants & Post Conviction Cases

When someone is facing criminal charges, the outcome of the case can depend heavily on the quality of the investigation behind the defense. In many situations, critical evidence is missed, witnesses are overlooked, or important facts are never fully examined.

At Kay & Associates Investigations, our experienced criminal defense investigators work with attorneys, law firms, defendants, and families throughout Los Angeles and Southern California to uncover facts, locate evidence, and help strengthen legal defense strategies.

Our criminal defense investigators handle cases discreetly, professionally, and with courtroom-focused investigative methods designed to support criminal defense and post conviction matters.

Whether you are defending against criminal allegations or reviewing a possible wrongful conviction, our investigative team is prepared to help.


Experienced Criminal Defense Investigators Since 1992

Kay & Associates Investigations is led by Andy Kay, a licensed California private investigator since 1992. Our agency has more than three decades of experience conducting complex criminal defense investigations throughout California.

Our criminal defense investigators have assisted in cases involving:

  • Violent crime allegations
  • Fraud and financial crimes
  • Narcotics investigations
  • Assault and self-defense claims
  • Theft and embezzlement accusations
  • Domestic violence allegations
  • Wrongful conviction reviews
  • Witness credibility investigations
  • Post conviction investigations

Every criminal defense investigation requires attention to detail, legal awareness, and strategic fact development. Our investigators understand the importance of uncovering information that may impact the outcome of a case.


What Criminal Defense Investigators Do

A criminal defense investigator works independently from law enforcement to gather evidence, verify facts, and identify information that may support the defense.

Our criminal defense investigators assist with:

Witness Location & Witness Interviews

Witnesses are often difficult to locate, unwilling to speak, or were never properly interviewed during the original investigation. Our investigators work to locate and interview witnesses who may provide critical information.

We investigate:

  • Contradictory witness statements
  • Timeline inconsistencies
  • Witness credibility concerns
  • Missed investigative leads
  • Potentially overlooked testimony

Independent witness interviews frequently uncover information that was not included in the original police investigation.


Evidence Review & Criminal Case Analysis

Many criminal cases involve evidence that was incomplete, misunderstood, or insufficiently analyzed. Our criminal defense investigators review available documentation and evidence carefully to identify inconsistencies and investigative gaps.

This may include:

  • Police report analysis
  • Surveillance footage review
  • Timeline reconstruction
  • Photographic evidence analysis
  • Digital communications review
  • Social media investigations
  • Background investigations

Our investigators help criminal defense attorneys build a clearer understanding of the facts surrounding the case.


Post Conviction Investigators in Los Angeles

Even after a conviction, new evidence can emerge that changes the understanding of a case. Our post conviction investigators work with attorneys and legal teams to help uncover facts that may support appeals, sentence modifications, or other post conviction relief efforts.

Post conviction investigations may involve:

  • Newly discovered evidence
  • Witness recantations
  • False accusations
  • Undisclosed conflicts or relationships
  • Independent fact verification
  • Contradictory evidence
  • New witness identification

Many post conviction cases depend on detailed investigative work and identifying facts that may have been overlooked during the original proceedings.


Criminal Defense Investigators for Attorneys

Criminal defense attorneys throughout Los Angeles and Southern California often hire independent criminal defense investigators because law enforcement investigations are not always complete.

Our criminal defense investigators assist legal teams with:

  • Defense strategy support
  • Trial preparation
  • Jury-related investigations
  • Witness impeachment research
  • Surveillance operations
  • Scene documentation
  • Background investigations
  • Independent evidence gathering

Our goal is to provide organized, legally obtained investigative information that can support defense counsel effectively throughout the legal process.
