MIAMI (WSVN) - The State Attorney’s Office provided an update on filing criminal charges against the suspect accused of murdering homeless men in Miami.

Back in December, 25-year-old Realtor Willy Suarez-Maceo was arrested for a string of murders.

A news conference was held Friday afternoon with Miami-Dade State Attorney Katherine Fernandez Rundle, City of Miami Mayor Francis Suarez and Miami Police Interim Chief Manuel Morales to discuss the updated charges.

The State Attorney’s Office said there is surveillance video of who they called a serial killer in action.

“We were able to discover a video of the shooting on Miami Avenue, where it revealed that a black vehicle had driven up to the location where the victim was laying down on the ground and shot at him several times,” said Morales.

Suarez-Maceo was previously facing charges of attempted murder, but he is now being charged with murder.

“Having an unknown killer striking out at random victims is like no other type of crime to solve,” said Fernandez Rundle.

Police said two homeless victims were shot and killed right before Christmas.

Suarez-Maceo was originally being connected to two of the three shootings, but officials were also investigating his possible connection to a stabbing back in October.

Officials released new video connected to the violent crimes.

The Oct. 16 video showed a man parking a black Dodge Charger in the same area where someone stabbed and killed a man in downtown Miami.

The footage shows someone walking toward that location about two minutes later.

“You will see him now coming back, running away from the scene, and again he’s captured on the security camera there,” said Fernandez Rundle.

On Dec. 21, another video clip showed a black Dodge Charger rolling up on a man sleeping on the sidewalk.

Prosecutors said the suspect shot the man, and he did not survive.

“The fact that this particular person preyed on the most vulnerable in our community is particularly upsetting,” said Suarez.

Authorities said that 9mm casings found at the scene matched casings of a similar scene from two hours prior that day.

Investigators said surveillance cameras near the crime scenes provided them with a clear license plate of the Charger, which is registered to Suarez-Maceo. He was arrested the next day.

While taking him into custody, authorities said, officers found a loaded Glock that was connected to the crimes.

“These types of anonymous, seemingly haphazard killings can create a real sense of fear and unease, so we are all here today to let our community know that these seemingly random killings have been solved, and they were committed by Willy Suarez-Maceo,” said Fernandez Rundle.

Suarez-Maceo has been charged with two counts of first-degree murder and one count of attempted murder.

He remains in jail with no bond.
