This assignment aims for you to evaluate the criminal investigations process. Here’s what happened: On September 13, 2004, Fred Smith approached Bill Jones's house requesting a ride to pick up money in a neighboring town. Smith offered to pay Jones $20 for gas and time. Jones accepted but mentioned he needed to pick up a friend, Roger Fish, along the way. The three drove to 200 S. Railroad Street, Brysonton, Roan County, where Smith exited the vehicle, approached the house, and engaged in a drug-related exchange that ended in a shooting: Smith shot Raynard Jenkins in the chest and attempted to shoot at Bob Marshall, who ran and escaped. Smith fled in a car with Jones and Fish but was pulled over by law enforcement shortly after. Witnesses identified Jones as the shooter. Smith, Jones, and Fish were arrested on murder charges.

The investigation involved law enforcement from the State Bureau of Investigation, the Sheriff's Office, crime scene processing, witness interviews, evidence collection, and forensic analysis. SA Pearson led the scene investigation, securing the scene, photographing and sketching it, and collecting evidence such as bloodstains, a plastic bag with drug evidence, and the suspect's firearm. SA Moss drafted and executed search warrants, coordinated follow-ups on leads, and oversaw evidence collection, including fingerprint and DNA evidence. The investigators documented their findings through photographs, sketches, notes, and evidence marking, crucial for courtroom presentation. The investigation resulted in recovered evidence linking Smith to the shooting, including gunshot residue, bloodstains, and fingerprints.

The comprehensive evaluation of the criminal investigation described demonstrates a combination of well-executed procedures and some procedural gaps. Proper crime scene management is fundamental for ensuring evidence integrity and admissibility in court. In this investigation, SA Pearson’s meticulous approach to securing the scene, photographing from multiple angles, and documenting evidence with scales and sketches aligns with best practices. The use of grids for bloodstain mapping and note-taking ensures detailed documentation that supports forensic analysis and court presentation (Saferstein, 2018). Furthermore, the collection and preservation of evidence, such as the Ruger firearm and bloodstain swabs, followed standard protocols, increasing the likelihood of successful forensic testing, including DNA analysis and ballistics examination (Swanson et al., 2017). Similarly, securing the scene with barriers and maintaining chain of custody are critical for evidence integrity, which appears to have been appropriately handled in this case.

However, certain areas reveal deficiencies and room for improvement. For instance, the investigation lacked a comprehensive collection of shell casings or projectile evidence—despite assertions that no projectiles were recovered. While it is possible evidence was genuinely absent, the absence of shells and bullets reduces the scope of ballistic analysis and may impact the strength of the case (Lloyd & Shyr, 2017). Additionally, the practice of disposing of witness notes after only typed-up versions raises concerns. Proper documentation requires maintaining original reports and interview recordings to prevent loss of details that could be critical during trial highlighting the importance of chain of custody and proper record management (Fisher et al., 2010).

The investigative process also demonstrates effectiveness through the systematic development of leads and follow-up by detectives. Assigning specific leads to individual investigators ensures accountability and thoroughness, which is commendable. Nevertheless, the somewhat hasty disposal of witness notes points to a lack of long-term case management planning. Implementing a case management system that retains all investigative notes and evidence documentation would support long-term cases, especially if they become cold cases, potentially decades later (Stickney & Hailing, 2014).

Regarding forensic analysis, the collection of blood and firearm evidence was properly executed, with chain of custody preserved through sealing and proper storage methods. However, the investigation could have benefitted from more advanced forensic procedures such as ballistics testing to match the firearm to potential projectiles or fired cartridge casings, which were not recovered at the scene. The absence of such evidence weakens the link required to establish the perpetrator’s direct involvement beyond witness testimony.

The investigation's handling of evidence also had room for enhancement. For instance, the bloodstain mapping was performed using a grid method, which is standard, but more precise digital mapping technologies could provide higher accuracy and clearer courtroom visuals (Olsen, 2017). Moreover, forensic testing on the bloodstain swabs—such as DNA profiling—was indicated but not explicitly detailed in the investigation summary. Ensuring comprehensive forensic testing and rigorous analysis could strengthen the case substantially.

In terms of procedural improvements, implementing standardized best practices like maintaining all witness notes, preserving physical evidence in secure conditions, and conducting extensive ballistic examinations would improve investigative robustness. Equally important is the use of modern forensic tools such as digital scene mapping, 3D laser scanning, and advanced DNA analysis that can provide conclusive kinship and matching evidence, thus bolstering the evidentiary chain necessary for conviction (Lien et al., 2018).

The role of documentation in a courtroom cannot be overstated. Properly documented crime scenes, evidence, and investigative steps form the backbone of establishing guilt beyond reasonable doubt. Photos, sketches, notes, and chain-of-custody records are crucial for cross-examination and defending the case in court (Gaines & Miller, 2017). Failure to preserve meticulous records risks challenges to findings, can undermine the prosecution, and may lead to case dismissal.

Finally, if a case remains unsolved for 30 years—becoming a cold case—additional components become vital for prosecution. These include preserved evidence suitable for modern forensic testing, such as DNA analysis, and detailed case files that can correlate old evidence with current databases. Advancements in forensic science, particularly familial DNA searches and databases like CODIS, increase the potential for solving cold cases by matching evidence to known profiles even decades later (Whitfield et al., 2019). Prosecutors also need to ensure that witnesses’ memories are preserved through interviews and that evidence remains in a secure environment for future testing.

In conclusion, while the investigation showcased commendable crime scene management and evidence collection practices, there are clear areas for improvement in long-term case management, thorough forensic analysis, and procedural adherence. The integration of advanced forensic technologies and meticulous documentation elevates the potential success of investigations and prosecution efforts. Continuous training and adherence to evolving best practices are imperative for law enforcement to effectively solve and prosecute complex criminal cases efficiently and reliably (Connors et al., 2016). A proactive approach to evidence preservation, detailed documentation, and leveraging modern forensic methods will ensure justice is served, even many years after the initial incident.
