as described as a high-capacity magazine, capable of holding 12 bullets, prosecutors said.

The unapprehended shooter took off heading towards 5th Ave. into the Taft Houses development and remained at large Sunday.

The two suspects were wearing black facemasks and multiple layers of clothes to avoid detection when they approached Jihad, prosecutors said, calling the killing  an orchestrated hit. 

A relative of Jihad's said the teen had engaged in an online feud before he was killed, although cops could not immediately confirm if that was the motive for the slaying.

 It was a beef on the Internet,  the relative said.  They were going back and forth and they're still trashing him now. 

 He was no gang member,  the relative said of Jihad.  He was a good boy. 

The two victims were both under the scaffolding but a few feet away from each other. The gunman was firing from east to west under the construction scaffolding, which stretches the length of three apartment buildings.

Cops were alerted to the shooting by ShotSpotter, a system of highly sensitive microphones positioned in the area designed to detect gunfire. When they arrived, they found the two gunshot victims.

The older victim was relaxing outside, smoking a cigar, when he was shot in the right hand and suffered a minor wound, his father, Clarence Gaines, told The News.

 I'm grateful they didn't get my son in the body,  Gaines, 79, said.  It's terribly sad about that little boy. He never got a chance to live his life.
