A Brighton District Court judge today ordered an Allston man held without bail at his arraignment on charges that he fatally stabbed a man who objected when the defendant threw a bottle at his girlfriend, Suffolk County District Attorney Daniel F. Conley announced.

JULIO “FREDDIE” MARISCAL (D.O.B. 12/1/70), a.k.a JULIO CUELLAR, was charged with murder for the April 3 stabbing death of 40-year-old Jose Mendoza Villalta of Brighton inside the defendant’s Mansfield Street home. Investigators believe the stabbing took place Saturday night after Mariscal’s girlfriend drank a toast with Villalta, prompting Mariscal to throw a beer bottle at her and Villalta to decry that act.

Assistant District Attorney Cory Flashner of Conley’s Homicide Unit told the court that, shortly before midnight on April 3, Boston Police officers received a call indicating that a man had been stabbed in the area of Mansfield and Lincoln Streets. Police officers who responded to the scene found the victim lying on the ground, “with blood coming from his upper left chest area,” Flashner said.

Emergency medical services responded to the scene and transported Villalta to Beth Israel Deaconess Medical Center, where he succumbed to his wounds, Flashner said. Villalta died “from a single stab wound to the chest,” Flashner said.

On the afternoon of April 4, Flashner said, the Boston Police Department received an anonymous phone call with helpful identifying information – including the defendant’s nickname “Freddie” – that led police to Mariscal’s home. Flashner told the court that the defendant lives “around the corner” from the location where the victim was discovered by police.

While police officers were at the defendant’s home, they saw a man riding his bike coming from the rear yard of the house. When officers asked for his name, “he responded that his name was Freddie,” but then said that his name was actually Julio, Flashner told the court.

As officers continued to talk to the man – later identified as the defendant – they observed that he had “a large, fresh cut on his hand,” Flashner said. This type of cut was consistent with the wound “that a person might receive as the hand slides down the handle of a blade as someone is plunging a knife into an object,” Flashner told the court.

During the course of the investigation, and after several interviews with witnesses, authorities determined that on the evening of the stabbing, the defendant, his girlfriend, the victim, and several others were at the defendant’s home drinking alcohol and socializing.

At one point, Flashner said, Villalta asked the defendant’s girlfriend to toast.

“The defendant observed the victim and [his] girlfriend having a toast, became very angry, and began to call his girlfriend hateful and disrespectful names,” he said.

The defendant and his girlfriend became involved in a verbal altercation, during which the defendant allegedly threw a beer bottle at her, striking her in the back.

“The victim, having observed this, told the defendant he should not act that way, and shouldn’t be treating a woman like that,” Flashner told the court.

This led to a verbal confrontation between the two men, Flashner said, and a decision to go outside and fight. Villalta and Mariscal started to walk to the door, when Mariscal turned and went into the kitchen, where he grabbed a knife.

“No blows had been struck,” at this point, Flashner said. The defendant then walked up to the victim with the knife in his hand and “punched the victim – but the punch was actually a stab,” Flashner told the court.

Mariscal is represented by attorney Denise Regan. He is expected to return to court on May 4.
