An East Boston man who fled the state and used an alias after allegedly gunning down Luis Raul Rodriguez in broad daylight was held without bail today following his arraignment in Suffolk Superior Court, District Attorney Daniel F. Conley announced.

The Suffolk County Grand Jury on Sept. 13 indicted JONATHAN CARVALHO (D.O.B. 10/29/89) on charges of first-degree murder and unlawful possession of a firearm for the 29-year-old Chelsea victim’s fatal shooting on Aug. 10. At the request of Assistant District Attorney Amy Galatis, Superior Court Clerk Gary D. Wilson ordered Carvalho held without bail, as Carvalho has been since his arraignment in Chelsea District Court six days later.

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 Rodriguez’s apartment door. When Rodriguez answered, Galatis said, the individual told him that Carvalho was waiting for him outside.

Carvalho and Rodriguez “had a previous disagreement in the weeks preceding the murder,” Galatis told the court.

Meanwhile, Galatis said, Carvalho was observed by witnesses “pacing and agitated in the parking lot of the building.”

After a short period of time, prosecutors say, Rodriguez left the apartment and went out to the parking lot. The defendant and victim “circled each other briefly before the defendant took a 9mm firearm from the area of his waist and fired it at Rodriguez,” Galatis said.

Although the victim turned and began running back into the building, “the defendant followed Rodriguez, arm outstretched with the firearm pointed at [him], and fired at him at least two more times,” Galatis told the court.

One of those shots hit Rodriguez in the back, piercing his lung. Rodriguez stumbled into the building and was able to make it up the stairs before collapsing inside of the apartment.

Rodriguez was rushed in an ambulance to Massachusetts General Hospital, where he died of his wounds a short time later.

Galatis noted to the court that, “by all accounts, Mr. Rodriguez neither showed nor had possession of a weapon.”

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 U.S. Marshals, Chelsea Police and State Police assigned to Conley’s office arrested Carvalho in Savannah, Georgia, on Aug. 12 and he was extradited to Massachusetts after waiving rendition proceedings. When arrested by local and federal authorities, he initially provided a false name of Shakoor Raheem.

Catherine Rodriguez is the DA’s assigned victim witness advocate. Carvalho is represented by attorney Willie Davis. He is expected to return to court on November 9.
