One person hospitalized, 5 arrested for assault and battery in connection with Winchester fight

Five people were arrested and charged with assault and battery and disorderly conduct after a fight at Shannon Beach in Winchester Sunday night in which multiple people were stabbed and one was taken to the hospital, according to State Police.

State Police spokesman David Procopio confirmed via e-mail Monday that one stabbing victim was rushed to Mass General Hospital Sunday night with non-life threatening injuries.

Juan F. Hernandez, 29, of Chelsea, was charged with six counts of assault and battery with a dangerous weapon and with disorderly conduct, according to a police report filed in Woburn District Court.

Hernandez had an outstanding default warrant out of Chelsea District Court for charges including assault and battery with a dangerous weapon, strangulation or suffocation, intimidation, and assault and battery on a family/household member, per the police report.


Cesar Amaya Fuentes, 35, Julio Lara Alas, 39, Victor Medina, 31, and Carlos A. Medina Banegas, 18, were charged with assault and battery and disorderly conduct in connection with the altercation, the report said.

A witness told police the incident began with an argument between Hernandez and a man inside another vehicle. Hernandez pushed open the passenger door of his car and hit the vehicle next to his. He then began arguing with the owner of the vehicle and allegedly punched him in the face.

Two other men, Medina Banegas and Medina, then allegedly got involved, according to the report. One witness told police that at some point Hernandez “retrieved a knife from his vehicle and began stabbing everyone involved,” according to the police report. Several witnesses told police that Hernandez allegedly began the violence and was responsible for stabbing multiple people.

Hernandez told police via translator that he was “jumped by” the owner of the car and was assisted by Medina, Hernandez’s brother-in-law, and Medina Banegas. Hernandez said during the altercation, he accidentally stabbed his brother-in-law, Medina, who said Hernandez was “swinging at everyone,” per the police reports.


When state troopers arrived at Shannon Beach at 8:14 p.m. Sunday, several people had stab wounds and assorted other injuries, including several individuals who were not charged. All were evaluated on scene by EMS staff, according to the report. Only one person was taken to the hospital.
