An East Boston man who fled the state last week after allegedly shooting Chelsea resident to death was ordered held without bail today at his murder arraignment, Suffolk County District Attorney Daniel F. Conley announced.

At a Chelsea District Court arraignment this afternoon, JONATHAN CARVALHO (D.O.B. 10/29/89) was charged with the Aug. 10 homicide of 29-year-old Luis Rodriguez. He was additionally charged with unlawfully carrying a firearm and unlawful possession of ammunition. District Court Judge D. Dunbar Livingston ordered him held without bail.

Assistant District Attorney Amy Galatis told the court that, at approximately 12:30 on the afternoon of the shooting, Carvalho went to the victim’s Central Avenue home with another individual. That individual knocked on Rodruiguez’s apartment door. When Rodriguez answered, the individual told him that Carvalho was waiting for him outside; the defendant and the victim had allegedly had a prior dispute in the weeks before the shooting.

Meanwhile, Galatis told the court, Carvalho was observed by witnesses “pacing and agitated” in the apartment building parking lot.

When Rodriguez went outside, Galatis said, he and Carvalho circled each other briefly before Carvalho removed a 9mm handgun from his waist area and fired on Rodriguez.

As Rodriguez turned and ran back into the building, the defendant allegedly followed him, arm outstretched, before firing two more shots.

“One of those shots hit Rodriguez in the back, piercing his lung,” Galatis said.

The victim stumbled into the building and was able to make it upstairs before collapsing inside of his girlfriend’s apartment.

Rodriguez was rushed to Massachusetts General Hospital where he was pronounced dead a short time later.

The defendant fled the scene and, later, the state. Investigators obtained a warrant for his arrest on the night of Aug. 10 and were able to track him to a bus headed to Florida.

With the assistance of US Marshals, Chelsea Police and State Police assigned to Conley’s office arrested him in Savannah, Georgia, on Aug. 12 and he was extradited to Massachusetts after waiving rendition proceedings.

Catherine Rodriguez is the assigned victim witness advocate. Carvalho is represented by attorney John Hayes. He is expected to return to court on September 17.
