A key witness testified in the trial for five of the 14 suspects accused in the death of Lesandro "Junior" Guzman-Feliz.

Kevin Alvarez, a known member of the Trinitarios gang, took the stand Monday to testify that the five defendants did kill Junior Guzman-Feliz.

Alvarez was charged with murder, manslaughter, and gang assault. He pleaded guilty to those charges a few weeks ago.

Fourteen suspects stand accused of dragging Junior out of a Bronx bodega and killing him with a machete last year.

Investigators believe Junior was targeted last June in a case of mistaken identity.

Nine other defendants will be tried at a later date.
