Miami-Dade Police Department

The Miami-Dade Police Department is one of the local agencies drawn into the investigation of the Cupid murders, a case whose expanding geography and lack of leads demanded sustained cooperation across police departments. Its contribution is shown less through a single commanding figure than through the shared machinery of the investigation: a multiagency task force, field operations, and crime-scene work that could document evidence even when it offered investigators little immediate progress.

Role in the Interagency Task Force

At the Governor’s request, the Florida Department of Law Enforcement provided a conference room at its Miami Regional Operations Center as headquarters for the Cupid task force. The full-time team eventually numbered twelve officers and detectives from five agencies: the Miami Beach Police Department, the City of Miami Police Department, the Miami-Dade Police Department, the North Miami Police Department, and the Florida Department of Law Enforcement. The Miami-Dade Police Department therefore worked within a coalition rather than conducting the investigation alone.

The task force’s headquarters grew with the case. At first, investigators had a standard-sized corkboard. After eight months, when six women had disappeared, three bodies had been found, and the team still had no leads, the Florida Department of Law Enforcement assigned Special Agent Dominick Falconetti and supplied a larger board. The room became a working archive: investigative folders, police reports, interviews, and boxes of victims’ personal records accumulated alongside computers and other office equipment. The Miami-Dade Police Department’s place in this shared effort linked local police work to a broader investigation spanning multiple jurisdictions.

Field Operations and Crime-Scene Work

A striking field contribution came during a Miami-Dade County Police Department SWAT training exercise. Before dawn, officers searching an abandoned United States Navy missile silo and warehouse near Florida City found the body of nineteen-year-old Marilyn Siban. The discovery began as part of a practice search: the officers opened the silo doors and investigated a makeshift enclosure inside the deserted structure before realizing that it contained a murder victim. Their training operation had unexpectedly brought one of the task force’s most important cases into view.

The discovery did not itself solve the murder. The Florida Department of Law Enforcement’s forensic team from Key West and the Miami-Dade Police Department Crime Scene Unit spent two days searching the surrounding area for trace evidence, including tracks and discarded objects, but found nothing. The location was remote, set away from main roads near the Everglades, and offered few obvious witnesses. Investigators expected the more extensive processing of the silo, warehouse, and perimeter to take five additional days, while Dominick Falconetti doubted it would yield useful evidence based on the results at earlier scenes. The department’s work is thus presented both as necessary evidence collection and as a measure of the case’s frustrating evidentiary limits.

That investigative method also appears in the search of William Rupert Bantling’s home. Miami-Dade crime-scene personnel worked alongside other investigators, treating ordinary household materials as potential evidence. They collected samples from the home, documented its rooms, and searched for traces that might connect the suspect to the murders. In Bantling’s master bedroom, Miami-Dade Police Department Detective Eddie Bowman and Special Agent Chris Masterson examined videotapes found in a decorative trunk. The scene illustrates the department’s participation in a coordinated search, where evidence could come from routine objects as well as from more conspicuous items.

Scale and Limits of the Investigation

The department’s role belongs to a case defined by both accumulating detail and persistent uncertainty. Investigators assembled victim records and crime-scene documentation, but the murders were spread across Miami-Dade County and the evidence gathered at scenes did not reliably identify the killer. In the search around Marilyn Siban’s discovery site, the forensic team and the Miami-Dade Police Department Crime Scene Unit found no useful tracks, clothing, weapons, or comparable trace clues. The work was extensive; its immediate yield was slight.

The broader task force faced a related problem: coordination could pool personnel and expertise, but it could not by itself establish that the same person was responsible for every crime or supply the missing physical link. The narrative distinguishes investigative hypotheses from proof, showing officers building a case through comparisons, records, witness interviews, and forensic examination. The Miami-Dade Police Department’s contribution is therefore grounded in concrete institutional labor—training operations, processing scenes, and examining evidence—rather than in a claim that the department alone directed or resolved the investigation.

Narrative Significance

The Miami-Dade Police Department represents the local, operational side of a widening murder inquiry. Its officers encounter the case in the field and its crime-scene unit works alongside state investigators, while detectives contribute to the examination of evidence recovered from the suspect’s home. These actions place the department inside the investigation’s daily process, not merely in the background of its institutional structure.

The contrast between the scale of that process and its uncertain results gives the department’s presence particular weight. A dozen investigators from five agencies, enlarged headquarters, extensive records, and days of scene processing all testify to the effort invested; the absence of decisive clues at the silo shows why effort did not immediately become resolution. The department’s part in the task force embodies the case’s central procedural reality: progress depended on shared work across agencies, while the evidence still had to withstand scrutiny before it could support a conclusion.
