Update: Miami Beach Police announced Friday that they had arrested Brown in Miami-Dade County.
The 32-year-old woman fatally shot near South Beach on Sunday was a cooperative witness in an active but separate human trafficking case, police announced Wednesday.
Latoya Michelle Wiggins was shot at least three times just after 2 a.m. near 10th Street and Collins Avenue. She died on the scene.
Police identified the suspect as Keith Brown, 33. The gunman and Wiggins had “some sort of altercation” prior to the shooting, police spokesman Ernesto Rodriguez said.
Rodriguez said police believe the gunman and the victim knew each other, but it remains unclear if her cooperation with police was connected to the shooting.
“We don’t know if the two are connected,” he said. “We don’t believe this was an isolated incident.”
Miami Beach police released surveillance footage Wednesday of the suspected gunman running from the scene. Officers recovered the gunman’s weapon, which he dropped near 11th Street.
