Miami Beach police said the footage reveals a brutal attack that left a couple hospitalized and led to the arrest of a 36-year-old man.

The incident occurred around 3 a.m. on Nov. 16 outside the News Cafe, located near Ocean Drive and Eighth Street.

Miami Beach police say John Albert Gladney Jr., who is listed as homeless in his arrest report, approached a woman sitting at one of the outdoor tables. They said Gladney made a comment to her, which prompted her partner, a man, to intervene and punch him in the face.

In retaliation, police said Gladney pulled out a knife and began slashing both victims, leaving them wounded on the street. Multiple surveillance camera angles captured the violent attack, showing Gladney wielding the knife as he assaulted the couple, according to investigators.

An arrest report states that bystanders quickly rushed to help, with one witness applying pressure to the man’s neck after seeing blood spurting from a deep wound.

Miami Beach police said officers responded promptly to the scene, where paramedics treated the victims before transporting the couple to Jackson Memorial Hospital’s Ryder Trauma Center.

Authorities said both victims, in their 30s, suffered non-life-threatening injuries. The woman sustained stab wounds to her right shoulder, under her right arm and near her left shoulder, while her partner was cut on the neck, back, and both sides of his chest, the report stated.

Investigators obtained additional surveillance footage, which showed Gladney running away from the scene with the knife still in his hand, heading toward a nearby block.

Detectives discovered that Gladney had dropped his cellphone and sunglasses at the scene. Using the cellphone as evidence, they were able to eventually track him down just a few blocks away from the crime scene, according to the report.

Gladney’s arrest report did not state the nature of the alleged comment toward the woman before the argument occurred.

Jail records show he is facing two counts of aggravated battery with a deadly weapon.

As of Tuesday, Gladney is being held without bond at the Metrowest Detention Center.

Beachfront high-rises in Miami that house thousands of residents and tourists are sinking at rates that surprised experts. Researchers found 35 luxury buildings in Surfside, Bal Harbour, Miami Beach, and Sunny Isles sank between 2016 and 2023 in a process called subsiding, the Miami Herald reports. Some sank by eight-tenths of a inch, while others sank more than 3 inches, according to a study published Friday in Earth and Space Science. “Almost all the buildings at the coast itself, they’re subsiding,” said Falk Amelung, a geophysicist who was the study’s senior author. “It’s a lot.”

It’s been known high-rise buildings settle by as much as several tens of centimeters during and immediately after construction, reports the University of Miami’s Rosenstiel School of Marine, Atmospheric and Earth Science—whose scientists conducted the study. But they found out the settling can go on for years. Experts aren’t sure of the implications, but several told the Herald this calls for more research and on-site inspections. The sinking could indicate that the rise in sea levels is accelerating the erosion of the limestone on which the area is built. Greenhouse gas emissions are driving the rise.

Researches began by looking at whether such sinking was behind the 2021 collapse of Champlain Towers in Surfside, deciding it wasn’t. But they found subsidence at other beachside buildings nearby. Sinking doesn’t always lead to structural problems. “Sometimes it can be dangerous, sometimes not—it will have to be evaluated,” said Shimon Wdowinski, a geophysicist at Florida International University. Researchers from other universities used other data and methods to validate the study’s findings. (More study stories.)
