Confession cases are some of the most difficult to defend; juries, judges prosecutors and even some criminal defense lawyers often believe that only guilty people confess to crimes. The Brendan Dassey case, shown in the Netflix Documentary "Making A Murderer" has highlighted the problem of coerced and false confessions. In the webinar we focus on both suppressing confessions and persuading juries that confessions are false.

Forensic DNA expert Tiffany Roy describes five common types of flawed forensic DNA testimony she encounters when she reviews transcripts of analysts’ testimony.

To combat questionable prosecution “expert” evidence, defense lawyers need to have a thorough understanding of Federal Rule of Evidence 702 and companion rules. This presentation provides practitioners with a framework for Article VII (Opinions and Expert Testimony) of the Federal Rules of Evidence, summarizes defense favorable cases, and presents arguments and tips on how to spot and avoid the most common ways the prosecution abuses expert testimony.  This area is of vital importance now considering the recent amendments to Federal Rule of Evidence 702.

When representing men accused of domestic violence, do lawyers consider hiring an expert for the defense? The authors note that experts can help attorneys and jurors better understand the role of stereotypes and how they play a significant role in domestic violence cases. Despite recent research finding that domestic violence is not necessarily a crime against women, the traditional ways of thinking about domestic violence continue to inform how cases are prosecuted.

Although voluntariness is a mainstay of the U.S. legal system, voluntariness and its flip side, coercion, are ill-defined. Likely because of this ambiguity, admissibility decisions for contested confessions have been inconsistent. Some modern-day, often-used interrogation techniques (e.g., investigators feigning friendship) are coercive, even if they appear innocuous and non-adversarial.

The aftermath of an accidental fire can often look the same as the aftermath of an intentionally set fire. This confounding fact has led to many false accusations. John Lentini writes that an arson determination should be viewed with great skepticism if it is based on (1) “low burning,” (2) a fire that burned “hotter than normal” or “faster than normal,” or (3) the appearance of “pour patterns” on a floor without a positive finding of an ignitable liquid in a laboratory test.

Modern technology used by the police (including drones and mobile device forensic tools) and ever-changing drug laws make suppression hearings more challenging for the defense team. Advocates must invoke the Fourth Amendment in a world much different from the one in which the amendment was drafted. The defense attorney must create a well-developed record in support of a client’s claims. One method of developing the record is the use of experts to explain changing science and technology.
