A disagreement over a gated fence outside a Miami-Dade home turned into an alleged sword threat Wednesday, when police say a property owner told a contractor he was going to shoot him twice in the head and then cut it off. The man, identified as Alvaro Alejandro Fonseca, was arrested and booked into jail on a felony charge after officers said he went inside his house, grabbed a sword, and returned to confront the worker.
A Routine Fence Job Turns Hostile
According to NBC 6 South Florida, police were called around 3:18 p.m. to the 1500 block of Southwest 122nd Avenue after a dispute broke out at the property. Officers said the confrontation began over a gated fence being built next to Fonseca's residence, and that he and the contractor became involved in a verbal argument before things escalated. The contractor told police that the property owner had obtained city permission to build the fence, according to the arrest report.
Instead of the dispute cooling off, police said Fonseca walked back inside his home and armed himself with a sword. He then allegedly threatened to shoot the contractor twice in the head and cut his head off with the blade, the outlet reported, citing the arrest report. The contractor told investigators he feared for his life during the exchange.
Contractor Documents the Confrontation
Rather than simply walking away, the contractor began recording the encounter, police said. He also snapped a photograph that investigators said showed Fonseca holding the sword, evidence that was later cited in the case against him. That documentation appears to have played a central role in building the charge police ultimately filed.
Fonseca was read his Miranda rights and denied making any threats, police said. But the arresting officer wrote that Fonseca's account of what happened was inconsistent, a detail that was noted in the report used to support his arrest.
Charges and Booking
Fonseca was charged with aggravated assault with a deadly weapon without intent to kill. Under Florida law, aggravated assault with a deadly weapon but without intent to kill is classified as a third-degree felony. He was booked into the Turner Guilford Knight Correctional Center, and records listed his bond as to be set.
Fence construction in Miami-Dade typically requires permits and adherence to local rules, with the county's own fences and gates guidelines laying out the permitting process property owners are expected to follow before installation begins. The contractor's claim that the homeowner in this case had city permission echoes that framework, though the dispute itself turned violent well before any paperwork questions could be sorted out peacefully.
The Miami-Dade Sheriff's Office
had previously posted a traffic alert on X, dated November 7, 2025, noting that police activity had shut down stretches of Southwest 122nd Avenue, Southwest 128th Street and the area near the Turnpike at Southwest 120th Street, urging drivers to seek alternate routes.
