Sgt. David “Randy” Dull

Sgt. David “Randy” Dull a veteran Baltimore City Police detective sergeant whose career in the Central District’s Major Crimes Unit spanned more than four decades of service, leadership, and quiet influence on generations of detectives. 

Long Career in Central Major Crimes

Sgt. Dull joined the Baltimore Police Department and built his reputation in the Central District, eventually becoming a key supervisor in the Central District’s Major Crimes Unit (MCU), later reorganized as the District Detective Unit (DDU). Alumni records list him specifically as “David Randy Dull – CD – MCU – DDU,” reflecting his long association with central-district investigations and his supervisory role there. 

Over more than 35 years of service, he became known as an experienced investigator who understood both the street-level realities of Central District crime and the demands of complex follow-up investigations. His work placed him at the center of major felony cases in downtown Baltimore, including robberies, shootings, and other serious offenses that routinely flowed to Central’s major-crimes detectives.

Leadership and Mentorship Style

Within the unit, Sgt. Dull developed a reputation as a working sergeant who stayed deeply involved in the details of his detectives’ cases. A 2015 department profile of one of his detectives, retired Detective Kenny Driscoll, notes that when “Detective Sergeant Randy Dull suggested an investigative avenue or next step, Kenny had already completed it or was working on it,” underlining both Dull’s active case oversight and the high standard he set for his squad.

Now, it’s time for Detective Kenny Driscoll to respond with his thoughts on Sgt. Dull. Kenny described his own style as often out-of-the-box, like being the first officer in the agency trained in SCAN (Scientific Content Analysis), a technique so new the agency refused to pay for it. When trained, SCAN came off as a linguistic polygraph, where only Kenny was trained and had to be taken at his word. Sgt. Dull was willing to take that risk and trust in Kenny’s ability. SCAN became a very powerful tool for the Baltimore Police. Kenny also introduced going after cloned phones to combat cell phone thefts, bait robberies, thefts from autos, and other Part One crimes related to cell phones, which reduced cell phone thefts. But before doing so, they went after bootleg music because it was a way to get probable cause to search cloned cell phone operations. Each step was a little more out-of-the-box, yet Sgt. Dull was open to this, and in the end, the efforts paid off. It seemed when new ideas came up to fight crime, Sgt. Dull—a stern leader—was open to giving these techniques a try. He seemed very forceful at times with his squad, but he was also very protective of his detectives. As a result, he often led a squad of investigators that had the best crime numbers in the city for solving crimes, closing cases, and obtaining confessions. He was well-respected, the kind of leader who had his men and women working harder because they enjoyed being thought of as some of the best.

In that same profile, Sgt. Dull described Det. Driscoll as the “truest sense of a cop,” emphasizing teaching, leadership, and sharing techniques like SCAN across the unit. That comment reflects Dull’s own philosophy: a belief that good detectives should not only solve cases but also pass on skills, building a stronger investigative culture in Central Major Crimes.

Dedication Beyond the Minimum

Accounts from the Baltimore Police Historical Society describe Sgt. Dull as having “more than 35 years dedicated service” and note that he often paid out of his own pocket for training or equipment to make things easier on himself and “his men.” That willingness to invest personal funds in equipment and professional development underscores how seriously he took his supervisory responsibilities and the welfare of his squad.

Those same historical notes portray him as a consistent supporter of the department’s history and alumni community, placing him among a group of veteran officers and supervisors who remained engaged with the agency’s legacy even as they neared or entered retirement.

Recognition for 43 Years of Service

By 2024, Sgt. Dull’s tenure had reached approximately forty-three years, an unusually long career even by veteran standards. In July 2024, a ceremony highlighted by command staff recognized Detective Sgt. Randy Dull with a Certificate of Appreciation specifically for his 43 years of service to the Baltimore Police Department. That public recognition from senior leadership, including a deputy commissioner, signaled how widely respected he was within the organization.

This formal acknowledgment complemented the quieter, day-to-day respect he earned in Central Major Crimes, where his guidance on cases, his expectations for thorough investigative work, and his commitment to his detectives left a mark on the unit’s culture.

Legacy in Central Major Crimes

Sgt. Dull’s legacy in the Central District’s Major Crimes Unit is twofold: he is remembered both as a seasoned supervisor who shepherded major felony cases for decades and as a mentor who helped shape the investigative skills of younger detectives. His name appears in alumni and historical records alongside other notable Central detectives and supervisors, reinforcing his standing in the department’s collective memory.

For many Baltimore officers and detectives who worked in Central, Sgt. Dull represents a model of the old-school detective sergeant: hands-on with cases, demanding but fair with his people, and deeply invested in both the craft of investigations and the well-being of his squad.
