Joshua Flores faces eight felony counts tied to the Oct. 4 attack, while all three stabbing victims have left the hospital.
BOSTON — A Brighton man accused of stabbing three men early Sunday is being held without bail pending a dangerousness hearing after prosecutors brought multiple felony charges against him following a separate machete-related arrest, according to police and court reporting.
Joshua Flores, 24, faces three counts of armed assault with intent to murder, three counts of assault and battery with a dangerous weapon causing serious bodily injury and two counts of mayhem in connection with the Oct. 4 stabbing. He also faces carrying a dangerous weapon and disturbing the peace charges stemming from his arrest four days later.
Judge Shelley Joseph ordered Flores held without bail pending a dangerousness hearing scheduled for Oct. 15, Boston.com reported. A dangerousness hearing allows a court to consider whether conditions of release can reasonably protect the public while a criminal case is pending. The charges remain allegations, and Flores has not been convicted in the case.
The stabbing investigation began at about 1:30 a.m. Oct. 4, when Boston police officers assigned to the Allston-Brighton district were called to the area of Cambridge Street and Harvard Avenue. Officers found three adult men suffering from stab wounds, police said.
Boston EMS transported the men to local hospitals with injuries police described as not life-threatening. CBS Boston reported Friday that all three victims had since been released and were expected to make full recoveries.
Four days after the attack, officers responded shortly before 5 p.m. to a report of a person swinging a large knife near Leo M. Birmingham Parkway and Waverly Street. Police said detectives encountered Flores in front of 444 Western Ave. and ordered him to drop the weapon.
Flores complied, and police recovered a machete from the sidewalk, according to the department. Officers said they also found a folding knife with reddish-brown stains in his pants pocket. Authorities have not publicly released testing results establishing the nature or source of those stains.
Police initially arrested Flores on the weapons and disturbing-the-peace charges. Detectives then developed probable cause to charge him in the earlier stabbing, the department said. CBS Boston, citing court documents, reported that Flores made statements to investigators acknowledging that he stabbed three people. Any such statement would be subject to the normal evidentiary process as the criminal case moves forward.
The reviewed reports did not establish a confirmed motive for the attack. They also did not indicate that prosecutors had proved a connection between the folding knife recovered Thursday and the injuries suffered Sunday. Those questions remain part of the developing criminal case.
Flores remained in custody as of the latest reports, with the Oct. 15 dangerousness hearing representing the next publicly reported court proceeding. It was not immediately clear whether an attorney for Flores had publicly responded to the allegations.
