Town resident, 31, also charged

UPDATED, Oct. 17:  Jonathan T. Perry, 17, of Somerville, has been indicted as a youthful offender and charged with manslaughter and assault and battery with a dangerous weapon causing serious bodily injury in connection with the Aug. 29, fatal shooting of Tenzin Kunkhyen, 16, of Malden.

In an Oct. 17 news release, Middlesex District Attorney Marian Ryan has announced that Perry expects to be arraigned in Cambridge Juvenile Court on Wednesday, Oct. 18.

In juvenile court, youthful-offender cases are open to the public.

A second individual, Keith R. Harlow, 31, was arrested Sept. 5 at the same Arlington apartment. The location was not identified, but a police log notes arrests at a Medford Street location.

In a Sept. 5 town news release, Chief Frederick Ryan reported the arrest by Arlington police investigators, working in conjunction with Somerville and State Police detectives. The news release does not name the suspect, because he is a juvenile, but he was previously identified by the DA's office.

The shooting took place at 14 Farragut Ave., in Somerville, four blocks from the Arlington border.

The release says he was  arrested without incident Sept. 5 He is being held on a warrant out of Middlesex Juvenile Court. 

He is to make a first appearance in Cambridge Juvenile Court, likely at an arraignment Sept. 6.

He is being held without bail pending arraignment. He also has an outstanding arrest warrant from Worcester Juvenile Court.

Harlow was held on three outstanding arrest warrants charging him with:

• Possession of a Class A Substance (Heroin)
• Resisting Arrest
• Disorderly Conduct
• Operating a Motor Vehicle with a Suspended License.

Report adds details reported Sept. 5 that shortly after Kunkhyen’s death, Harlow had posted a television news report about the shooting to Facebook and wrote above the link, "I never wanted this day to come but when [your] sister told me what you was doing i knew it was just a matter of time."

Harlow did not elaborate in his posting, the website reported.

Also Tuesday, the website said, a friend of Kunkhyen's who performs rap music under the moniker Gold Brick Ghost said in an email that acquaintances believe the shooting was accidental.

"They were friends and everyone knows it was an accident man," the musician, who says on Twitter that he is based in Florida, wrote, according to “[P]erry aint no killer and definitely dident [sic] kill his best friend man.”

Harlow's Facebook posts identifies him as "R. Keith Harlow."

Earlier report 

An Aug. 30 Globe report said the victim is of Tibetan heritage, had moved from India, had gone to Somerville High and later to Malden High. 

Shortly before 5 p.m. Aug. 29, Somerville police responded to a Farragut Avenue residence for reports of a shooting and found the teen suffering from an apparent gunshot wound. The victim was transported to Mount Auburn Hospital, where he was pronounced dead.

A preliminary investigation suggests that the victim was in the residence with other individuals who were known to him and that this is not a random act, a statement from District Attorney Marian Ryan says.

No one has been charged. Conducting the ongoing investigation are Ryan's office, State and Somerville Police. The circumstances surrounding how the shooting occurred are part of this investigation. The identity of the victim was withheld pending official identification from the Office of the Medical Examiner and notifying next of kin.

The DA's office reported no other updates in the investigation on Wednesday, Aug. 30.
