Montgomery Mayor Steven Reed described four people arrested in connection with last weekend’s riverfront brawl as “assailants who come from out of town to cause chaos and sow divisiveness.”

Reed and the Montgomery Police Department on Friday released an update to the ongoing investigation, saying police detectives have conducted frame-by-frame analysis of the videos of the brawls and extensive interviews with witnesses and victim Harriott II Co-Captain Damien Pickett.

“This case is not quite yet closed, but our message is clear,’’ Reed said. “In Montgomery, not only will we protect our team members, but we will protect our citizens.”

“If you violate the sanctity of our community and the safety of our citizens,’’ the mayor said, “then you will be brought to justice.”

Four people were arrested throughout the week following a Saturday confrontation on the city’s riverfront between crew of the Harriott II and the occupants of a private pontoon boat who authorities said refused to move to allow the riverboat to dock in its regular slot.

A now-notorious melee ensued including punches and even a chair, all caught on multiple cell phone videos.

So far, four people have been charged: Mary Todd, 21, third-degree assault; Richard Roberts, 48, two counts of third-degree assault; Allen Todd, 23, one count of third-degree assault, and Zachery “Chase” Shipman, 25, one count of third-degree assault.

All charges are misdemeanors and all four have been booked.

Pickett, a Black man, along with a 16-year-old white young man, were victims in the fight. All of the suspects charged so far are white.

Authorities on Friday said a former person of interest, a white man seen on the videos shirtless with sunglasses around his neck and wearing a blue and white ball cap, has been cleared of criminal wrongdoing and is cooperating with the investigation.

The man, city officials said, was attempting to de-escalate the situation, according to testimony from Pickett and analysis of video by Montgomery investigators and partner agencies.

“This is a fluid investigation. At this point, the FBI has not classified these attacks as a hate crime, but the investigation is ongoing,’’ Reed said.

“As a former judge and as an elected official, I will trust this process and the integrity of our justice system.”

“However, my perspective as a Black man in Montgomery differs from my perspective as mayor,’’ Reed said.

“From what we’ve seen from the history of our city — a place tied to both the pain and the progress of this nation – it seems to meet the moral definition of a crime fueled by hate, and this kind of violence cannot go unchecked.”

“It is a threat to the durability of our democracy,” Reed said, “and we are grateful to our law enforcement professionals, partner organizations and the greater community for helping us ensure justice will prevail.”
