Cordero-Stutz said a man -- who the M-DSO later identified as Steven David Rustrian-- was involved in the crash, got into a fight with Jaramillo, disarmed him, and used his service weapon to shoot him several times.

Rustrian, 21, of Miami-Dade’s South Miami Heights neighborhood, then “entered his own vehicle and took his own life,” Cordero-Stutz said. “Good citizens who did see what happened called 911.”

The shooting was shortly after 3:50 p.m. at Southwest 122 Avenue and 128 Street, near the Florida Turnpike, in southwest Miami-Dade County’s Three Lakes neighborhood, according to deputies.

Miami-Dade Fire Rescue personnel took Jaramillo to HCA Florida Kendall Hospital, where he died, according to deputies. He was 27. Cordero-Stutz described him a a homegrown hero.

“Devin was an amazing officer, hard working ... He is what we call a legacy kid because his father was on the job for so many years,” Cordero-Stutz said. “He was strong, he was a helper, he was a supporter.”

Sources told Local 10 News Reporter Glenna Milberg on Friday that Jaramillo’s father, David Jaramillo, was a retired M-DSO detective who had served as the president of the Hispanic Police Officers Association.

Deputies and police officers arrived at the hospital on Friday afternoon. Some hugged. There were tears. A group of motormen escorted a M-DFR ambulance transporting Jaramillo’s body in a flag-draped casket to the Miami-Dade County Medical Examiner’s Office.

A sea of red and blue lights filled the street as hundreds of members of the law enforcement community gathered outside to pay their respects.

Cordero-Stutz said the procession to escort Jaramillo’s casket from the medical examiner’s office to a funeral home will likely be later on Saturday.

Cordero-Stutz also said there was “a second subject” in custody who was involved in the crash. M-DSO later announced “he was released, and no formal charges were filed at this time.”
